News: Transport related to Chalmers University of TechnologyFri, 11 Sep 2020 10:32:53 +0200 of Advance Award for wireless centre collaboration<p><b>​Collaboration is the key to success. Jan Grahn and Erik Ström, who have merged two Chalmers competence centres, GigaHertz and ChaseOn, to form a consortium with 26 parties, know this for sure. Now they receive the Areas of Advance Award 2020 for their efforts.</b></p>​<span style="background-color:initial">A competence centre is a platform for knowledge exchange and joint projects. Here, academia and external parties gather to create new knowledge and innovation. The projects are driven by need, and can be initiated from industry – who have a problem to solve – or from the research community, as new research results have generated solutions that may be applied in industry.</span><h2 class="chalmersElement-H2">Stronger as one unit</h2> <div>The competence centre GigaHertz focuses on electronics for high frequencies, while ChaseOn focuses on antenna systems and signal processing. They overlap in microwave technology research, which is relevant for communication and health care, as well as defense and space industry. And even if some areas differ between the two centres, numerous points of contact have been developed over the years. The two directors – Jan Grahn, Professor at Microtechnology and Nanoscience, and Erik Ström, Professor at Electrical Engineering – saw that close collaboration would result in obvious advantages. In 2017, the two centres therefore formed a joint consortium, bringing together a large number of national and international companies.</div> <div>“Formally, we are still two centres, but we have a joint agreement that makes it easy to work together”, says Erik Ström.</div> <div>“For Chalmers, it is a great strength that we are now able to see the whole picture, beyond departmental boundaries and research groups, and create a broad collaboration with the companies. This is an excellent example of how Chalmers can gather strength as one unit”, says Jan Grahn.</div> <h2 class="chalmersElement-H2">Multiplicity of applications</h2> <div>Technology for heat treatment of cancer, detection of foreign objects in baby food, antenna systems for increased traffic safety, components to improve Google’s quantum computer, 5G technology and amplifiers for the world’s largest radio telescope… The list of things that have sprung from the two competence centres is long. The technical development has, of course, been extreme; in 2007, as GigaHertz and ChaseOn were launched in their current forms, the Iphone hit the market for the very first time. Technology that today is seen as a natural part of everyday life – such as mobile broadband, now almost a necessity alongside electricity and water for most of us – was difficult to access or, at least, not to be taken for granted.</div> <div>The companies have also changed, which is noticeable in the flora of partners, not least for GigaHertz.</div> <div>“In the early 2000s, when our predecessor CHACH centre existed, the collaboration with Ericsson was dominant. Today, we collaborate with a much greater diversity of companies. We have seen an entrepreneurial revolution with many small companies, and even though the technology is basically the same, we are now dealing with a multiplicity of applications”, says Jan Grahn.</div> <div>As technology and applications developed and changed, the points of contact between the two centres grew, and this is also what initiated the merger:</div> <div>“When we started, in 2007, we were competing centres. The centres developed completely independently of each other, but have now grown into one. The technical convergence could not be ignored, we simply needed to start talking to each other across competence boundaries – which in the beginning was not so easy, even though today we view this as the obvious way forward”, says Erik Ström.</div> <h2 class="chalmersElement-H2">Research to benefit society</h2> <div>The knowledge centres are open organisations, where new partners join and collaborations may also come to an end. Several companies are sometimes involved together in one project. Trust and confidence are important components and take time to build. One ground-rule for activities is the focus on making research useful in society in the not too distant future.</div> <div>Chalmers Information and Communication Technology Area of Advance can take some of the credit for the successful collaboration between GigaHertz and ChaseOn, according to the awardees.</div> <div>“Contacts between centres were initiated when I was Director of the Area of Advance”, says Jan Grahn.</div> <div>“The Areas of Advance show that we can collaborate across departmental boundaries, they point to opportunities that exist when you work together.”</div> <h2 class="chalmersElement-H2">They believe in a bright future</h2> <div>The competence centres are partly financed by Vinnova, who has been nothing but positive about the merger of the two. Coordination means more research for the money; partly through synergy effects and partly by saving on costs in management and administration.</div> <div>The financed period for both GigaHertz and ChaseOn expires next year. But the two professors are positive, and above all point to the strong support from industry.</div> <div>“Then, of course, we need a governmental financier, or else we must revise the way we work. I hope that Vinnova gives us the opportunity to continue”, says Erik Ström.</div> <div>“The industry definitely wants a continuation. But they cannot, and should not, pay for everything. If they were to do so, we would get a completely different type of collaboration. The strength lies in sharing risks in the research activities by everyone contributing funds and, first and foremost, competence”, says Jan Grahn.</div> <h2 class="chalmersElement-H2">“Incredibly fun”</h2> <div>Through their way of working, Erik Ström and Jan Grahn have succeeded in renewing and developing collaborations both within and outside Chalmers, attracting new companies and strengthening the position of Gothenburg as an international node for microwave technology. And it is in recognition of their dynamic and holistic leadership, that they now receive the Areas of Advance Award.</div> <div>“This is incredibly fun, and a credit for the entire centre operation, not just for us”, says Erik Ström.</div> <div>“Being a centre director is not always a bed of roses. Getting this award is a fantastic recognition, and we feel great hope for the future”, concludes Jan Grahn.<br /><br /><div><em>Text: Mia Malmstedt</em></div> <div><em>Photo: Yen Strandqvist</em></div> <br /></div> <div><strong>The Areas of Advance Award</strong></div> <div>With the Areas of Advance Award, Chalmers looks to reward employees who have made outstanding contributions in cross-border collaborations, and who, in the spirit of the Areas of Advance, integrate research, education and utilisation.

For example, it is critical that robots get to weld the components properly. In the DIAS project, Chalmers latest research results are used in modeling alternative concepts enabling digital experimentation of alternative product architecture, with Fraunhofer's expertise in simulating robotic paths, and Cambridge's expertise in interactive decision-making and modeling-based risk analysis.<br /><br /></div> <div><br /><em>–    We have a unique opportunity to combine the latest achievements from Chalmers, Fraunhofer FCC and Cambridge, into a new and powerful way to support GKN Aerospace in their integration of next generation technologies already in the concept phase, says Ola Isaksson, researcher at Chalmers and leader of the consortium.</em><br /><br />GKN Aerospace Sweden AB in Trollhättan is responsible for critical engine components of Open Rotor engines. Ultimately, the goal is to enable the methods developed in the DIAS project to enable GKN Aerospace to offer the technologies demonstrated in Clean Sky in future business.<br /> <br /><em>–    We are very happy that this Chalmers led consortium won this Call for Partners.

In June, the collaboration agreement was renewed for another three years.</b></p><div>​<span style="background-color:initial">The new agreement – signed by Chalmers' President Stefan Bengtsson and Mats Moberg, Senior Vice President Research &amp;Development at Volvo Cars – implies that Volvo Cars continues to be one of Chalmers so-called strategic partners. The strategic partnerships are characterized by extensive research collaborations, joint educational initiatives, and a diversity in collaboration across Chalmers research disciplines as well as focus on highlighted topics (<a href="/en/collaboration/strategic-partnerships/Pages/default.aspx">read more about the strategic partnerships here</a>).</span></div> <div><span><h2 class="chalmersElement-H2">&quot;Chalmers takes an exceptional position&quot;</h2></span></div> <div>The academy is central for Volvo Cars, and will remain so in the future, says Mats Moberg:</div> <div> </div> <div> “For our provision of competence through excellent educational programmes, for the present through lifelong learning, and for our future development as a company with knowledge through collaborations in research and innovation. As a university, Chalmers takes an exceptional position as our main collaboration partner in all these areas”, he says, and continues:</div> <div> </div> <div>“We collaborate in student thesis projects, courses and educational programmes. Volvo and Chalmers work together in international projects, from the United States in the west to China in the east, and 60 percent of our industrial PhD students in Volvo Cars Industrial PhD Program – VIPP, which we established in 1999 – are now enrolled at Chalmers.”<br /><br /></div> <div> </div> <div>The great collaboration is not only due to the fact that Chalmers is close to Volvo Cars head office as the company is global, Mats Moberg points out.</div> <div> </div> <div>“It is simply because Chalmers offers both excellency and relevance in collaboration forms that have worked splendidly and enduring over the years.”</div> <h2 class="chalmersElement-H2">Major and rapid changes in the transport system</h2> <div> </div> <div>The first partnership agreement was signed with Volvo Cars back in 2013. The company is today one of Chalmers’ largest strategic partners, says Sinisa Krajnovic, Director of Chalmers Transport Area of Advance. The renewal of the agreement means an opportunity to further develop the partnership.</div> <div> </div> <div>“We are in a time period with major and rapid changes in the transport system, including new technologies and mobility behaviors. The collaboration with Volvo Cars gives us an expanded opportunity to develop our research and education, and our utilization within the transport system, making us even more able to contribute to the development of sustainable, road-safe and efficient transport.”</div> <div> </div> <div><br />For Chalmers, the strategic partnerships are a tool for updating research and education, ensuring the research to be conducted at the forefront, as well as offering education to the very best future engineers. Through the partnerships, strategies are synchronized and the parties also have the opportunity to build joint infrastructures and test beds that would not have been possible without continuous dialogue.</div> <div> </div> <div><div>“In my opinion, the Areas of Advance have an important role to play in coordinating, as hosts of the partnerships”, says Sinisa Krajnovic.</div> <h2 class="chalmersElement-H2">Electrification and automation important areas</h2></div> <div> </div> <div>Chalmers and Volvo Cars already have a multitude of joint investments in research infrastructures, competence centers and research projects.</div> <div> </div> <div>“We also look forward to working together in the new, big investment in electromobility research, SEEL – Swedish Electric Transport Laboratory – where Volvo Cars plays an important part. Electrification is an important area of collaboration for both Chalmers and Volvo Cars, as well as automation”, says Sinisa Krajnovic.<br /><br /></div> <div> </div> <div>And Mats Moberg agrees:</div> <div> </div> <div>“The renewal of our agreement is a confirmation of our mutual ambition to further sharpen our collaboration. This to continue towards added excellency, and to continue our work towards our goal of a sustainable, safe and personal mobility, but also to be leading in electrification, autonomous drive and digitalization.”<br /><br /></div> <div> </div> <div>The renewed agreement is for three years, and automatically extended for another two years thereafter.<br /><br /></div> <div> </div> <div>Text: Mia Malmstedt</div> <div> </div> <div>Photo: Erik Axén, Volvo Cars</div> <div> </div> <div>​<br /></div> <div> </div>Fri, 26 Jun 2020 16:00:00 +0200 system that understands human behavior will save cyclists<p><b>​In the project MICA, sponsored by FFI, researchers from Chalmers have investigated the interaction among cyclists and vehicles. They have developed a smart safety system that could reduce the number of fatal accidents in traffic with cyclists involved by up to 96 percent.</b></p><p>​The smart safety system continuously predicts what a driver should do to overtake a cyclist safely. The system acts when it sees a mismatch between what the driver does and what she or he should be doing. By collecting data from a test track, researchers have investigated how different factors affect behaviour in overtaking manoeuvres with oncoming traffic. Based on the data, the researchers have modelled how vehicles approach cyclists and integrated the models in frontal collision warnings and automatic emergency braking systems. The safety benefits from the systems have been evaluated through virtual simulation. </p> <p><span style="background-color:initial">“The smart collision warning alone promises a reduction of cyclists fatalities by 53-96 percent and a reduction of cyclists serious injuries by 43-93 percent” says Marco Dozza, professor at the Division of Vehicle Safety. </span></p> <h2 class="chalmersElement-H2"><span>Supports the Swedish car industry</span></h2> <p>The research results support the Swedish car industry in maintaining its world-leading role in designing advanced solutions for active safety. The models developed in the project can predict the driver's intention when approaching a cyclist from behind to perform an overtaking. These models can be integrated with existing systems and provide input on how an automated vehicle should safely and comfortably overtake a cyclist. </p> <p><span style="background-color:initial">&quot;Our research supports the development of safety systems that can help a driver or an automated vehicle interact with cyclists safely. We have taken the driver models from a TRL level of 1-2 to a TRL level of 5 for this scenario&quot; says Marco Dozza. </span></p> <p><span style="background-color:initial">TRL, Technology Readiness Level is a designation for a technology's maturity and associated technological risk.

This was the assignment from Volvo Penta, and students from Chalmers and Penn State University worked together to solve the problem. The result was award-winning!</b></p>​<span style="background-color:initial">Boats powered by electricity have become increasingly popular over the last years, but most marinas lack sufficient infrastructure to meet the need for charging. With this problem at hand, Volvo Penta announced a bachelor thesis last fall to get suggestions for solutions. The proposed project was a so-called Capstone project, and as such part of Chalmers strategic partnership with the Volvo Group, and to be carried out by students at Chalmers along with students from Penn State University in Pennsylvania, USA.<br /><img class="chalmersPosition-FloatRight" src="/SiteCollectionImages/Areas%20of%20Advance/Transport/_puffbilder/AgnesAime_350.jpg" alt="" style="margin:5px" /><br /></span><div><div>As a result, four students from Chalmers and four from Penn State have worked together in this project throughout the spring. And even though the Corona pandemic got in the way of the travel plans, it has been a successful collaboration – in fact, so successful that the students’ Solar Wharf Garage was awarded with first price in the Lockheed Martin Best Project Award. This is the second time a Capstone project wins first price since the start of the collaboration six years ago.</div> <h2 class="chalmersElement-H2">&quot;Project of good quality&quot;<br /></h2></div> <div>Agnes Tunstad and Aime Vesmes were part of the winning team. Initially, they were both attracted by the opportunity to gain international contacts, but that’s not all:</div> <div>“It seemed to be a fun project, and the collaboration with a global industry did not make it any less interesting”, says Aime Vesmes, and Agnes Tunstad nods and adds:</div> <div>“I like boats, and I like renewable energy! In addition, the project seemed to be of good quality.”<br /><br /></div> <div>Aime Vesmes is ending her third year at Mechanical engineering – together with the other two from Chalmers, Gustaf Malmsjö and Johan Kinell – while Agnes Tunstad is studying Automation and mechatronics. The project therefore entailed not only cooperation across national borders, but also across Chalmers’ programmes.</div> <div>“Much of the content is the same in our courses, but there is also a lot of differences. I’m happy for everything that this project taught me about the product development process, as this was completely new to me. Had it not been for my project colleagues from Mechanical engineering, this would have been much more difficult”, says Agnes Tunstad.<img class="chalmersPosition-FloatRight" src="/SiteCollectionImages/Areas%20of%20Advance/Transport/_puffbilder/Hamn_350.jpg" alt="" style="margin:5px" /><br /><br /></div> <div>The project has required a lot of learning, and a lot of time for feasibility studies for all of them:</div> <div><div>“Yes, the real challenge has been to learn everything we needed to know. For example, I didn’t know how solar cells worked, or what to think about in a marine environment. We have really learned along the way”, says Aime Vesmes.</div> <h2 class="chalmersElement-H2">Two-boat garage with 18 solar panels</h2></div> <div>The final product is a two-boat garage where the boats are charged by nine solar panels each. According to the calculations, the payback period is 13 years, and the estimated structural lifetime more than twice as long. The material choices for the garage are guaranteed to hold the least possible risk of rust or other damage, and the panels can also be folded down to protect them from hard weather.<br /><br /></div> <div>Their collaboration has been performed via Zoom, a digital tool for video communication. The eight students were careful not to divide the project into smaller pieces but to try – as far as possible – to cooperate in all parts. This is reflected in the report, they say; otherwise the report could have ended up “choppy”, as a reflection of the fact that different parts were carried out by different persons. The group believe that this is one of the reasons why they won the award. And as Agnes Tunstad says:</div> <div>“What’s the point of a global project if you do not work together?”<br /><br /></div> <div>The response from Volvo Penta has been nothing but positive. In the beginning, the students were in close contact with their contact person, but he also emphasized that he did not want them to be too influenced.</div> <div><div>“If our ideas can bring value to Volvo, I’m happy. That’s what it is all about; for us to be able to give ideas for solutions”, says Aime Vesmes.</div> <h2 class="chalmersElement-H2">Changed plans for the exhibition an advantage</h2></div> <div>The plan was for the Chalmers’ students to travel to Penn State in April. The trip had to be cancelled, for obvious reasons. But the restrictions imposed by the Corona pandemic have not only been negative. For the project participants at Chalmers, winning the award became even more fun as they were able to participate in a video presentation at the virtual exhibition from which the winner was selected.</div> <div>“Had it just been an exhibition with posters, as it usually is, it probably wouldn’t have felt as satisfying. In that case, we simply would not have been as involved. But now, thanks to the video, we were all included on equal terms”, concludes Agnes Tunstad.<br /><br /></div> <div>Note: <a href="">Watch the students’ video presentation here!​</a><br /><br /></div> <div>Text: Mia Malmstedt</div> <div>Photo: Charles Strömblad (photo of Agnes Tunstad and Aime Vesmes) and Gustaf Malmsjö (Solar Wharf Garage and Öckerö marina) </div> <div>​<br /></div> Thu, 28 May 2020 12:00:00 +0200 leads the way forward<p><b>​Fully electrified bus traffic on several routes, procurements of a record number of electric buses, indoor bus stops and countless tests.

Scientists at Chalmers and Xi&#39;an Jiaotong University, China now present a new way of taking this promising concept closer to large-scale application. An interlayer, made of a spreadable, ‘butter-like’ material helps improve the current density tenfold, while also increasing performance and safety.​​​​​​​​</b></p><div><span style="background-color:initial"><img src="/SiteCollectionImages/Institutioner/F/350x305/Shizhao_Xiong_350x305.jpg" class="chalmersPosition-FloatRight" alt="Porträtt av forskaren Shizhao Xiong " style="margin:5px;width:170px;height:150px" /><div>“This interlayer makes the battery cell significantly more stable, and therefore able to withstand much higher current density. What is also important is that it is very easy to apply the soft mass onto the lithium metal anode in the battery – like spreading butter on a sandwich,” says researcher Shizhao Xiong at the Department of Physics at Chalmers.</div> <div><br /></div> <div>Alongside Chalmers Professor Aleksandar Matic and Professor Song's research group in Xi'an, Shizhao Xiong has been working for a long time on crafting a suitable interlayer to stabilise the interface for solid state battery. The new results were recently presented in the prestigious scientific journal Advanced Functional Materials.</div> <div><br /></div></span><img src="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/solidstatebatterilabb750x.jpg" class="chalmersPosition-FloatLeft" alt="Bild från batterilabbet på Fysik på Chalmers." style="margin-top:5px;margin-bottom:5px;margin-left:10px;height:263px;width:350px" /><span style="background-color:initial"><div>Solid state batteries could revolutionise electric transport. Unlike today's lithium-ion batteries, solid-state batteries have a solid electrolyte and therefore contain no environmentally harmful or flammable liquids.</div> <div>Simply put, a solid-state battery can be likened to a dry sandwich. A layer of the metal lithium acts as a slice of bread, and a ceramic substance is laid on top like a filling. This hard substance is the solid electrolyte of the battery, which transports lithium ions between the electrodes of the battery. But the ‘sandwich’ is so dry, it is difficult to keep it together – and there are also problems caused by the compatibility between the ‘bread’ and the ‘topping’. Many researchers around the world are working to develop suitable resolutions to address this problem.</div> <div><br /></div> <div>The material which the researchers in Gothenburg and Xi'an are now working with is a soft, spreadable, ‘butter-like’ substance, made of nanoparticles of the ceramic electrolyte, LAGP, mixed with an ionic liquid.

Solutions are being developed and implemented, but climate-saving technologies and choices exist already today.

Many industries need biomass to reduce their emissions. It can be used for example as a fuel in the production of asphalt, cement and steel, for electricity production or as a vehicle fuel. Already today Sweden imports 95 per cent of the raw materials needed for transport biofuel because it is cheaper than using domestic material. It is hardly a sustainable solution when more and more countries import biomass. Ida believes that we need a coherent national strategy for biomass production and use.<br /></div> <div> </div> <div> </div> <div> </div> <div> </div> <div>“Where there are fossil-free alternatives, such as electrification, these should be used. But then the politics must clearly steer towards such a development. Otherwise, the biomass will simply go to the one who pays the most and not to where it would have the best use.”</div> <div> </div> <div> </div> <div> </div> <h2 class="chalmersElement-H2">Further areas for improvement</h2> <div> </div> <div> </div> <div> </div> <div>Another area for improvement could be the recycling of asphalt, explains Ida Karlsson.<br /></div> <div> </div> <div> </div> <div> </div> <div> </div> <div>“The legislation for this has recently changed but new, more efficient ways of working are not yet fully implemented. There are also different technologies to choose from depending on the quality of the tarmac, how heavy the vehicles which travel the route are and so on. Recycling requires energy but can still reduce emissions considerably, since asphalt is largely made up of bitumen, a variant of crude oil.” <br /></div> <div> </div> <div> </div> <div> </div> <div> </div> <div>Concrete is another major source of emissions. In Sweden, cement clinker is used as a binder in infrastructural concrete, but in other countries, materials such as slag from steel production or fly ash from coal-fired power plants is used as partial replacement of cement clinker, reducing emissions considerably.</div> <div> </div> <div> </div> <div> </div> <div>“Here we must dare to recognise the long positive experiences from its use in other countries, like Norway, and adopt these techniques and measures even if they have not been used before in Sweden.”</div> <h2 class="chalmersElement-H2"> </h2> <h2 class="chalmersElement-H2"> </h2> <h2 class="chalmersElement-H2"> </h2> <h2 class="chalmersElement-H2">Time to take a clear path forward</h2> <div> </div> <div> </div> <div> </div> <div>Ida Karlsson calls for clear plans, first until 2030, then onwards to 2045 as well.</div> <div> </div> <div> </div> <div> </div> <div> </div> <div>“If you already know what you want in 2030, you can make demands today. And then companies can also know that ‘OK, if we have to be able to meet these requirements by 2030, then we have the opportunity to invest in technology to achieve that’. Because large investments will be needed to change production and haulage operations. Then you have to make sure that there are requirements, needs, incentives and not least that there is climate neutral electricity available.”<br /></div> <div> </div> <div> </div> <div> </div> <div> </div> <div>“The transformative solutions - electrification, carbon capture, carbon-free steel and concrete - require time and significant investment. But if we have already picked the low hanging fruits, the cost increase for the transformative solutions need not be so great. That is why the low-hanging fruits are so important to get started with, because they make it easier cut emissions further in the future, at a lower cost.”</div> <div> </div> <div> </div> <div> </div> <div> </div> <div><div><strong>For more information, contact:</strong></div> <div>Ida Karlsson</div> <div>PhD student, Department of Space, Earth and Environment, Chalmers University of Technology</div> <div><a title="mail" href=""><span>​​</span>​</a><br /></div> <div>+46317726517</div></div> <div> </div> <div> </div> <div> </div> <div><br /> </div> <div><strong>Text: </strong>Christian Löwhagen </div>Mon, 18 May 2020 00:00:00 +0200 conference on innovations for wind ship propulsion<p><b>​The latest scientific and technological research in the field of sailing will be presented in June, when Chalmers University of Technology hosts an international conference, INNOV’SAIL 2020.</b></p><div>There has always been a great interest on improving the technology and performance in elite sail racing, for example, the Olympics, America's Cup and Volvo Ocean Race and now there is also a growing interest from shipping companies to use wind power on vessels to reduce fuel consumption and environmentally harmful emissions.

This gave Green Cargo the clear sign to use stronger locomotives, with just a few restrictions from the Swedish Transport Administration.</b></p>​In the short term, it means millions of Swedish crowns in savings. In the longer term, it strengthens the competitiveness of train transport and enables the transfer of transport from road to rail. This means reduced carbon dioxide emissions for heavier transport. <div><br /></div> <div>The classification of railway vehicles affects the distances they can operate. The freight train operator Green Cargo needed to install locomotives with greater traction to get a reasonable economy in their freight transport. This meant that heavier locomotives with three-axis bogies would have to operate lanes that were normally operated by lighter, two-axis locomotives. However, the Swedish Transport Administration could not allow the heavier three-axis locomotives to traffic the lanes if the safety could not be guaranteed. The situation was so critical that it became a standing point at the meetings between the Swedish Transport Administration's Director General and Green Cargo's CEO. </div> <div><br /></div> <div>The classification of Green Cargo's three-axis locomotive meant that the locomotive was in a higher class than many lanes have been classified for, which could mean low operating speeds. For bridges, calculation tools are available to analyze the impact of specific vehicles, but for geotechnics the situation was more complicated. An analysis may require expensive and cumbersome soil samples and the remaining geotechnical restrictions were numerous. <img src="/SiteCollectionImages/Institutioner/M2/Nyheter/andersekberg.jpg" class="chalmersPosition-FloatRight" alt="Anders Ekberg" style="margin:5px" /><br /><br /></div> <div><span style="background-color:initial">Anders Ekberg is the director of the competence center Chalmers Railway Mechanics (Charmec). He says that the main challenge for Charmec was to understand the problem. But with the help of the contacts and the understanding built up between Charmec's partners, a solution was soon to be found. </span><br /></div> <div><br /></div> <div>“In a few meetings with intermediate analyzes, we were able to gain insight through the experience and knowledge we have gained in previous projects. Once the solution method was identified, we could relatively easily reach a solution using our numerical tools” says Anders Ekberg. </div> <h2 class="chalmersElement-H2"><span>In-house models from Chalmers provided a solution</span><span>​</span></h2> <div>The researchers from Chalmers proposed a comparative analysis between the stress resulting from a two-axis locomotive and that of a three-axis locomotive. Using in-house models their analysis showed that the marginally lower load per axis of the locomotive actually made the resulting stress in the ground lower for the three-axis locomotive despite this loco having an additional axle. To further analyze load, the Swedish Transport Administration conducted a dynamic analysis using software developed within Charmec.​</div> <div><br /></div> <div>“The analysis supported the conclusion that the locomotives provided a lower load on filling material and the underlying soil. The Swedish Transport Administration was now able to reduce the number of restrictions for Green Cargo's three-axis locomotives” says Ibrahim Coric head of Maintenance Railway system Permission Construction at the Swedish Transport Administration. </div> <div><br /></div> <div>Markus Gardbring is head of Green Cargo's operations and believes that it is of great importance for their operations. </div> <div><br /></div> <div>&quot;Green Cargo can now use stronger locomotives and demolish a large number of circulations for a number of larger customers, which leads to more efficient freight transport and is a prerequisite for us to be able to have more goods on the railway&quot; says Markus Gardbring. </div> <h2 class="chalmersElement-H2"><span>Contributes to reduced carbon dioxide emissions</span><span>​</span></h2> <div>Another benefit is that heavier locomotives with more redundant traction slip less, which reduces maintenance costs. Markus Gardbring also sees gains in the longer term. The Swedish rail network is being rebuilt to allow longer trains. The Swedish government has decided to reduce 70 percent of all carbon dioxide emissions for heavier transport by 2030. The segment that can easily be transferred to rail is intermodal goods. Longer trains are more cost-effective and a prerequisite for enabling competition with trucks in an extremely competitive market. The traction force of the locomotive will be decisive as the weight rather than the length becomes limiting for the number of wagons per train.</div> <h2 class="chalmersElement-H2">Read more about Charmec</h2> <div><a href="/en/departments/m2/news/Pages/Railway-researchers-awarded-for-societal-impact.aspx">Railway researchers awarded for societal impact​</a><br /></div> <div><a href="/en/departments/m2/news/Pages/European-railway-harmony-better-for-the-climate.aspx">European railway harmony is better for the climate​</a><br /></div> <div><a href="/en/departments/m2/news/Pages/Prediction-of-cracking-increases-the-railway%27s-reliability.aspx">Prediction of cracking increases the railway's reliability​</a><br /></div> <div><a href="/en/departments/m2/news/Pages/CHARMEC---A-prerequisite-for-a-functioning-railway.aspx">CHARMEC - A prerequisite for a functioning railway​</a><br /></div>Wed, 06 May 2020 00:00:00 +0200 for electromobility gets 575 million SEK<p><b>​One of Europe’s leading testbeds for electric and charging vehicles is now one step closer to realisation.

This is shown in a new study by researchers from Chalmers and University College London, who also warn that self-driving vehicles could increase both energy consumption and emissions from passenger transport.– On average, about 1.5 people travel in each car in industrialized countries. But that number could actually decrease to less than one person per car, when automated vehicles enter the market. This could lead to a tripling in light-duty vehicle energy intensity, says Sonia Yeh, at the department of Space, Earth and Environment.</b></p><div>Occupancy is a central concept when it comes to calculating and assessing energy consumption and emissions for passenger transport. If you drive a car alone, the occupancy is 1 person kilometer per vehicle kilometer, or 1pkm/vkm. With two people in the car, the occupancy rate increases to 2 pkm/vkm. But there are also trips that have fewer than one person in the car. Sonia Yeh, professor in the division of Physical Resource Theory explains:</div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/SEE/Profilbilder/Sonia_Yeh_170.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />– In taxi travel, we don’t count the driver. For example, if a taxi driver drives 15 km to pick up a passenger,  and drive the customer 20 km to the destination, and drive another 5 km to finish the shift and go home. Since half the trips is empty, the trip average occupancy is 0.5, or 0.5 passenger kilometers for every vehicle kilometer. So the problem with taxi, some shared mobility, and automated vehicles, is that there are a lot of “empty miles” to pick up or drop off passengers or moving vehicles around. This could lead to even a tripling in light-duty vehicle energy intensity, an increase that would be difficult to compensate by fuel-saving technology.</div> <div><br /></div> <div>An increased occupancy rate in the cars would reduce both emissions and energy consumption per passenger kilometer, but the occupancy has instead decreased for the last several decades due to the increase of two car household for example. Today, there are really no examples where that trend has been broken.</div> <div><br /></div> <div>– Price based incentives, such as making single driver rides more expensive or shared rides cheaper, can be implemented. But previous studies show that people are generally not very sensitive to price, especially if they have to wait longer or if the trip takes longer. says Sonia.</div> <div><br /></div> <div>– Public transportation in Sweden has very low GHG emissions in general. To reduce transport GHG emissions further, the most effective strategies are to reduce trip distance, decarbonize fuels and increase occupancy. The current situation with the corona pandemic makes the situation trickier, as people are avoiding public transportation or shared mobility to reduce transmissions. There remains the hope for electric vehicles powered by fossil-free electricity to reduce greenhouse gas emissions from passenger transport.</div> <div><br /></div> <div>Sonia Yeh and her colleague at University College London, Andreas W Schaefer's, article “<a href="">A holistic analysis of passenger travel energy and greenhouse gas intensities</a>” was recently published in Nature Sustainability.</div> <div><br /></div>Fri, 24 Apr 2020 07:00:00 +0200 for transport research projects<p><b>​Transport AoA is now presenting a new call for project proposals.

Chalmers University of Technology is now entering into a new collaboration between companies and institutes in Sweden and India, as the sole Swedish academic party. The collaboration will improve traffic safety and provide the basis for new innovations and knowledge exchange.​</b></p>​<span style="background-color:initial">On Thursday, 20 February, a collaboration agreement was signed to mark the start of Sitis, the Sweden-India Transport Innovation and Safety Partnership. This agreement brings together leading Swedish and Indian companies and institutes in a long-term and global cooperation.<br /><br /></span><div>“The aim of this collaboration is to become a prominent platform for applied research and innovation in the area of safe and sustainable transport,” says Chalmers President Stefan Bengtsson, and continues:</div> <div>“Traffic safety is an urgent and immediate concern in all parts of the world and is also critical in driving a nation’s prosperity. We are now very happy to enter into a bilateral partnership that will address key traffic safety challenges in India and Sweden.”<br /><br /><img src="/SiteCollectionImages/Areas%20of%20Advance/Transport/_bilder-utan-fast-format/rickshaw_300.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" /></div> <div><div><div>The collaboration's outlines have been worked out over the past year, with Chalmers involved from day one. Both overall content and potential individual projects have been discussed. For Chalmers, the Sitis partnership is similar to an agreement with China, the China-Sweden Research Centre for Traffic Safety, which was signed in 2012.</div> <h2 class="chalmersElement-H2">Different strengths</h2></div></div> <div>Through Safer – the Vehicle and Traffic Safety Centre at Chalmers – which brings together 35 parties from academia, industry and society, Chalmers has extensive experience of collaborations in the field of traffic safety. Magnus Granström, Director at Safer, points out that both Sweden and India have high capacity to develop technology, concepts and solutions. But the competence lies partly in different areas. Sweden is globally renowned for work on traffic safety, while India has a strong IT and computer science sector.<br /><br /></div> <div>“Chalmers can contribute with, for example, knowledge on intelligent transport systems, artificial intelligence and cyber security, road safety research and knowledge of how to establish test beds. These are strong areas for us,” says Magnus Granström.</div> <div><div>“We see a clear advantage to having a platform for cooperation with Swedish companies and institutes around challenges in India. Chalmers already collaborates with several of the parties involved through the Safer competence centre, and with Sitis in place we can now further develop these collaborations. The agreement also allows us to find new Indian parties to work together with.”</div> <h2 class="chalmersElement-H2">A new set of challenges</h2></div> <div>India is a huge and fast-growing country, with considerable gaps between the high and low educated, and major challenges in the transport sector. The Sitis partnership will build a deeper understanding of road safety in the country. This also provides insights into the core challenges of other fast-growing economies with similar problems, and potential solutions can be developed.</div> <div>“We will be able to benefit from learning the needs in a country so different from ours, in terms of both culture and infrastructure. How is a transport system developed in such a country? How do they serve the population with freight and passenger transport? These questions need to be answered in order to build a sustainable and prosperous society,” says Magnus Granström.<br /><img src="/SiteCollectionImages/Areas%20of%20Advance/Transport/_bilder-utan-fast-format/SITIS_Sinisa_300.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" /><br /></div> <div><strong>FACTS: Sitis, </strong><span style="background-color:initial"><strong>Sweden</strong></span><span style="background-color:initial"><strong>-</strong></span><span style="background-color:initial"><strong>India Transport Innovation and Safety</strong></span><span style="background-color:initial"><strong> </strong></span><span style="background-color:initial"><strong>Partnership</strong></span></div> <div>Sitis was launched in Stockholm on the third global conference on road safety within the UN.
