Mercedes-Benz is world’s first car manufacturer to X-ray a crash test

The technical sensation begins with a very loud bang. At 60 km/h, a device with a crash barrier rams into the orange C-Class saloon and hits it full on the side. Crash tests are always something special – even for the experts. But the really spectacular part of this side impact test is located in a frame on the hall ceiling above the vehicle: A linear accelerator serves as an X-ray camera. Together with the Fraunhofer-Institute for High-Speed Dynamics, the EMI (Ernst Mach Institute) in Freiburg, Mercedes-Benz has now carried out the world’s first X-ray crash with a real car. On board was one SID II dummy on the left-hand side facing the impact. This is a test specimen with a female anatomy, specially designed for side impact tests.

Mercedes-Benz is the first car manufacturer to carry out an X-ray crash test. Its partner in the X-ray crash test is the Ernst Mach Institute of the Fraunhofer Gesellschaft. In the crash test, all processes in vehicle structures and dummies are visible for the first time. A powerful linear accelerator generates up to 1,000 high-resolution images per second.

This technology demonstration (proof of concept) at the EMI research crash facility in Freiburg has shown that high-speed X-ray technology can be used to visualise highly dynamic internal deformation processes. Previously invisible deformations and their exact processes thus become transparent. The numerous, high-resolution images allow precise analysis.

“The Mercedes-Benz X-ray crash sets a milestone in the development tools of the future. With a direct view into the hidden interior, it can help to draw important conclusions for the further improvement of vehicle safety. Mercedes-Benz thus confirms its role as a safety pioneer in automotive engineering.” Markus Schäfer, Member of the Board of Management of Mercedes-Benz Group AG, Chief Technology Officer

“The successful X-ray crash provides us with valuable insights to further optimize our technology for capturing previously inaccessible information. Fraunhofer EMI is thus consistently pursuing its strategy of using high-speed X-ray imaging to make dynamic processes visible.” Dr. Malte Kurfiß, Head of Crash Test Centre, Fraunhofer EMI

“The world’s first X-ray crash shows that X-ray technology can provide revealing new insights. We learn what happens inside a vehicle and to the dummies during an accident. The X-ray images also offer the opportunity to further improve the model quality of the digital prototypes.” Prof. Dr Paul Dick, Director of Vehicle Safety, Mercedes-Benz AG.
