Railway research and crash safety on IVA's 100 list

​Two research projects from the Department of Mechanics and Maritime Sciences are included on IVA's 100 list 2020. The list highlights current research and makes it easier for researchers and companies to find each other to create innovation and new business opportunities.
Every year the Royal Swedish Academy of Engineering Sciences (IVA) releases a list of the 100 research projects that have the most potential to translate research into utilisation and increased competitiveness for Swedish industry. In 2019, the focus area was digitization. This year's list, 2020, highlights research that links to sustainability.

Two research projects from the Department of Mechanics and Maritime Sciences have been placed on the list. The projects come from the Division of Vehicle Safety, which has partnered with Volvo Cars to develop an anatomical shoulder for crash dummies. And from the Division of Dynamics and the National Centre for Railway Mechanics Charmec, who developed virtual tests for crack formation in the rail.

"This is a fantastic acknowledgement that the research we conduct really benefits society," says Angela Hillemyr, head of department and responsible for utilisation at the Department of Mechanics and Maritime Sciences.

Artificial dummy shoulder saves lives

Although standardized crash tests have made car journeys considerably safer over the past 30 years, they have not been totally comprehensive – especially not for oblique frontal collisions. Researchers at Chalmers have developed a crash test dummy that now sets a new, life-saving standard for safety in passenger cars.

“We wanted to contribute to a new test standard for oblique collisions. The dummy used previously turned out to be too rigid in the shoulder and did not give a fair representation of how an actual person reacts to a crash that throws the body forward obliquely”, says Mats Svensson, professor at the Department of Mechanics and Maritime Sciences.

Prediction of cracking increases the railway's reliability

Cracking in rails and wheels is one of the largest maintenance costs for railway traffic. It is also the reason for many delays and stops that can lead to considerable costs for both train companies and track managers. But through methods developed at Chalmers, which predict cracking in rails and wheels, train traffic is now more reliable and environmentally friendly.

Anders Ekberg is a professor at the Department of Mechanics and Maritime Sciences and director of Charmec:

“More and more railway traffic occupy the same network, which leads to smaller windows for maintenance. But by being able to predict cracking, the risk of operational disturbances, unplanned maintenance and environmental impact is reduced. Then the costs can also be kept down. And that is a necessity for a functioning and efficient railway”, he says.
