For example, chemical propulsion (used to propel the space shuttle in 1969) is too costly and has the big disadvantage to consume a lot of propellant to reach long distances.

Furthermore, we can make use of the only energy source available in the solar system: the sun.    </div> <div><br /></div> <div>At the same time, the space industry is in the middle of a transition.

There are major societal challenges where research collaboration with industry is important. Since Sweden has the ambition to become the world's first fossil-free welfare state, it requires development in many areas. The research on lightweight materials and lower fuel consumption is an example.”<br /><br />What issues are relevant now, given the situation in the outside world?
<br /><br />&quot;The worst threat right now is whether we enter a trade war. Sweden is very dependent on exports and about half of our GDP come from exports. In addition, 70% of the export go to the EU's internal market, so when Britain leaves, it becomes an extremely difficult challenge for Sweden. For example, the UK is our largest exporting country for services. And cooperation between universities and industries will also be complicated.”

<br /><br />&quot;What I've heard about today has been incredibly exciting. I hope I get the opportunity to visit Chalmers again, Ann Linde concludes.<br /><br /><em>Text and photo: Carina Schultz</em><br />Thu, 06 Sep 2018 00:00:00 +0200 honorable appointed to CIRP Fellow<p><b>​Professor Rikard Söderberg has been appointed as Fellow of the International Academy of Production Engineering, CIRP.

It has gone from simpler simulation where details have been assumed rigid, to more advanced finite element (FEM) based simulations.</div> <div>-    The work of recent years has been aimed at driving simulation models for non-rigid geometry as digital twins in the future. It could mean an ability to control both the production process and product development in a more efficient way, says Professor Söderberg.<br /></div> <h5 class="chalmersElement-H5">Faster algoritms demands</h5> <p class="chalmersElement-P">However, in order to fully exploit the simulation models for geometry assurance as digital twins - both in production and in early stages of development - it is necessary to develop further. The project is therefore divided into three parts: <span></span></p> <div>The first part project focuses on better material models and finding faster algorithms for real-time use. This means refinement of the digital twin to handle more advanced material properties as multi-material solutions, i.e. solutions in which different materials are used in the same subassembly or the same component. Residual stresses, depending, for example welding details, also affects the geometrical deviation and variation and must therefore also be included in the simulations.</div> <div>-    This means more complex and demanding calculations. Therefore, we need to develop high-speed algorithms for real-time use, says Söderberg.<br /></div> <div><h5 class="chalmersElement-H5">Visualization necessary for decisionmaking</h5> <div>To use the digital twin as a decision tool, you need to visualize the variation as realistic as possible. Therefore, in the second part of the project, you enhance the simulation models with Raytracing, 3D scanning / point clouds and digital environments.</div></div> <div>Raytracing means increased realism when visualizing manufacturing variation and can be used to support decision-making in the early stages. Scanning results as point clouds are currently used to measure and verify components and products with great accuracy. Point clouds can be used to compare variations in batch details, but the method requires faster and more efficient algorithms due to the large amount of data.</div> <div>Finally, there is a need for models of digital environments visualizing the impact of manufacturing variations on perceived quality.<br /></div> <div>-    To effectively visualize geometric variation, models are required, as well as design and data to be combined into scenarios that then are evaluated. If we manage to automatically generate those models, we would significantly rationalize the geometry insurance process. We benefit greatly from the research on visual evaluation conducted by the department within the research area Percieved Quality, says Rikard Söderberg.</div> <div>In the third and final subproject, a preliminary study of a digital information flow, a so-called “Digital Thread”, is being planned.

He is also brave. Facing over a hundred top notch digitalization researchers and industrialists at the Wingquist Laboratory annual seminar, he claimed that “you’ve all misunderstood digitalization”.</b></p>​Digital technologies are transforming business models and industries at an ever-faster pace. As a response, every industry is catching up with a “digitalization” strategy. The problem though, is that we’ve completely misunderstood the concept of digitalization. Ashkan Fardost is a scientist, TEDx speaker and nominated as Speaker of the Year with a passion for how digitalization affects human behavior. Ashkan Fardost was also the opening keynote speaker at this year’s Wingquist Laboratory annual seminar.<br /><br />In what sense is digitalization misunderstood? Ashkan Fardost said that the basic misconception lies in the difference between digitization, which is making numbers of analogue things, vs digitalization, which is when we use human needs as a base for new technology, not just adding a sensor to an existing product.<br /><br />- Human needs existed long before we knew anything about technology. When the basic needs started to become fulfilled, the human developed and eventually technology became an extension of our human capabilities. However, the human is the only creature that is aware of its mortality – which is why we seek immortality through different projects.<br /> <br /><img src="/SiteCollectionImages/Centrum/Wingquist%20laboratory/DSC07778_rikard-ashkan-230x134.png" class="chalmersPosition-FloatRight" alt="" style="margin:5px 10px" />Some of the immortality projects Ashkan Fardost mentioned was book writing, being part of something bigger as a family, a religion or an organisation, or committing to science. But how do these projects relate to the digitalization era? <br /><br />- The internet lets you to create your own immortality projects, instead of picking something from the shelf. Back in the 50’s, the world was filled with “normal” people. Nowadays, weird is the new normal. The behaviour has changed. If you have a peculiar interest, the internet has made it possible for you to find equals around the world. The internet has created a global digital tribal society. A tribe that gives and receives help, co-creates with each other – for each other. The internet has killed the need to be normal and therefore the need for customized products will increase rapidly.<br /> <br />Ashkan Fardost concluded his talk by recommending companies that want to embrace this accelerating future to focus on behaviour trends instead of technology trends.<br /><br /><em>Text: Nina Silow</em><br /><em>Photo: Marcus Folino</em><br /> <br /><br />Fri, 27 Apr 2018 01:00:00 +0200 twins enhance quality via simulation<p><b>​Industry is continuously seeking efficient solutions that save time and improve quality. A five-year project in the Wingquist Laboratory focuses on simulations using digital twins, which will lay the foundations for the self-compensating factory.</b></p>​<br />The Wingquist Laboratory at Chalmers University of Technology in Gothenburg has focused on research in the field of digital product realisation since 2001. A key area in this laboratory is geometry assurance, which aims to minimise the impact of geometric variation in the final assembled product.<br /><br />- This area is a key one for industry and specific to mass production, where all the parts need to fit together and be interchangeable, says Professor Rikard Söderberg, Director of the Wingquist Laboratory, and continues:<br />- In industry, variation is traditionally handled by specifying tolerances, that is to say how much variation is permitted. Tight tolerances often make production expensive, since a high degree of precision is required in the production process.<br /><br />The geometry assurance software RD&amp;T, which was partially developed at Chalmers, has been used by Volvo since 1998 and also by a large number of companies globally.<br /><br />- RD&amp;T is now being further developed so that it can be used as a digital twin of the production system we would like to control. We can then regard RD&amp;T as a digital copy of the actual system, with the capability for real-time optimisation and control, Söderberg says.<br /><br />About a year ago the centre was awarded a large research project, Smart Assembly 4.0, by the Swedish Foundation for Strategic Research (SSF). The five-year project focuses on the geometry assurance process and has as its vision the self-compensating factory.<br /><br />- By using simulation in RD&amp;T along with new capabilities for rapidly scanning component parts, in future it will be possible to take into account geometric variation and adjust the assembly process to compensate for this, he says, and continues:<br />- This may involve matching the right bits together, adjusting fixtures and equipment and choosing the right sequence in spot welding, for example. By feeding a simulation model with real-time data, it can be used as a digital twin which will be used in practice to control the process.<br /><br />Söderberg, who has carried out research on simulation support for geometry assurance over more than 20 years, takes a confident view of the wave of digitalisation that is now washing over the industry.<br /><br />- This wave of digitalisation will increase access to data. And with more input data we will produce better simulation solutions. All companies face competition and want to benefit from smart working methods, Söderberg says, and continues:<br />- Industry as a whole is becoming more and more interlocked. The companies we work with have a number of subcontractors that manufacture components.<br /><br />- In future we may receive measurement data relating to components for a Volvo from suppliers and can use the information to make preparations before they are assembled. In the complex networks leading to a business transaction, there is a great deal of data that allows us to get the best out of the end product. If we can communicate digitally and optimise production and the production system without physical meetings and manual data processing, we can save a great deal of time.<br /><br /><span><span><em>Photo: Anna-Lena Lundqvis</em></span>t<br /><br /></span><a href="" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" /><span>Smart Assembly 4.0<span style="display:inline-block"></span></span></a><br /> <br />Thu, 26 Apr 2018 00:00:00 +0200 Volvo XC40 design ranked high by professor<p><b>​In a recent interview in the daily newspaper of Göteborgs Posten, professor Rikard Söderberg described the newest Volvo XC40 model as &quot;robust with a premium feeling&quot; - two characteristics that are studied in the Wingquist Laboratory research theme, Perceived Quality.</b></p><a href="">​Read the full interview on the GöteborgsPosten web. </a><div><br /></div> <div><a href="/en/centres/wingquist/research/research-themes/Pages/perceived-quality.aspx">Read more about the researc​h performed in the area of Perceived Quality.</a></div>Wed, 27 Sep 2017 00:00:00 +0200 Bengt Lennartson elected as a Fellow of IEEE<p><b>​From January 2017 Bengt Lennartson is IEEE Fellow for his contributions to hybrid and discrete event systems for automation and sustainable production.</b></p>​IEEE Fellow is the highest grade of membership in the world’s largest technical professional organization, given to persons with an outstanding record of accomplishments in any of the IEEE fields of interest.<br /><br />Bengt says that his two main results that motivate this grade are a computational method to perform stability analysis of hybrid systems, something he developed together with one of his first PhD students Stefan Peterson 20 years ago, and energy optimization of robot systems that was initiated by General Motors six years ago, and recently was implemented together with Kuka and Daimler in the EU project AREUS.<br /><br /><a href="/sv/personal/redigera/Sidor/bengt-lennartson.aspx">Read more about Bengt Lennartson and his research &gt;&gt;</a><br /><a href="">IEEE webpage &gt;&gt;</a><br /> Mon, 28 Nov 2016 00:00:00 +0100 student exchange<p><b>​​​During three months, the Wingquist Laboratory have hosted two master students, Luciano Filice  and Claudio Contreras, from University of Naples &quot;Federico II”, Italy.</b></p><span style="background-color:initial">Their specialization are Mechanical Engineering for Design and Production.

One thing that is vital when looking into energy systems is looking at the whole picture, what is input and what is output. Details are also crucial of course, but sometimes smaller details distract from seeing what the real problem is. That is what I enjoy working with, working with the bigger picture, not just focusing on details. Within Dimensional Management or Geometry Assurance we are connected to all phases within product development. I have also worked as a Design Engineer and Methods Developer within Saab prior to my current position.</div> <div><br /></div> <div><strong>What are your expectations on the collaboration with the Wingquist Laboratory VINN Excellence Centre?</strong></div> <div>- Collaboration with Chalmers, other universities and other industries are important for us at Saab. We are continuously working with improving tools and methods and participation in the centre is a significant part of that work. For us, currently working hard with Geometry Assurance and the processes and tools connected to this area, we feel that Saab has the right collaboration partners in this centre. It is also a strength to be part of a collaboration and take part in the knowledge transfer between the different types of industrie​s gathered within the centre, like IKEA, Volvo and Sandvik.</div> <div><br /></div> <div><strong>In what research themes are you participating?</strong></div> <div>- We are participating in Platform-based Development, Smart Assembly and Perceived Quality, with projects concerning aviation technology.  An example is aircraft doors. They need to be both be safe and look safe, combined with good aerodynamic properties. Perceived Quality, besides from the design aspects, can be seen as pure functional requirements as well.</div> <div><br /></div> <div><strong>What kind of industrial challenges do you foresee?</strong></div> <div>- I think one challenge is to use digital data in a smart and efficient way with the aim of reducing cost for the companies and to produce new products faster  still and fulfill all requirements. As an example, we want to be able to reuse data during the complete product development and get away from manual managing of digital data as much as possible.​</div> <div><br /></div> ​Fri, 08 Jul 2016 10:00:00 +0200 member of the board​<p><b>Lars-Åke Grundmark, CEO of VA Automotive, is a new member of Wingquist Laboratory VINN Excellence Center&#39;s board of directors.

Steven highlighted how Geometry assurance and sustainable design is related and why geometry assurance matter in today’s world. He explained that conversations and research about tolerancing are distantly removed from contemporary issues like climate change, sustainable energy, and international security. Steven means that we need to take a step back and see how tolerance decision-making and geometry assurance activities fit into the big picture, namely by focusing on the product development process.</div> <div><h2 class="chalmersElement-H2">Industrial perspective </h2></div> <div>The first day of the conference was packed with interesting presentations divided into three different tracks. The last presentation was from an industrial perspective held by Sandra Kronholm, Manager of Robust Design and Casper Wickman, Technical Leader within Craftmanship and Ergonomics at Volvo Cars. Together they gave the audience an insight about the challenges within geometry assurance at Volvo Cars, for example that one of the most severe challenges within operational development at Volvo Cars is the aim to reach the 20 months time plans in 2020.
