Abstract

The passive safety of passenger cars in frontal collisions is usually assessed by means of crash tests against a flat or angled rigid barrier. With respect to the frequency of asymmetrical frontal impacts in real world accidents, the most important crash test at Mercedes-Benz is an offset test with 40% overlap at 55 km/h against the rigid barrier. The rigid barrier should be replaced by a deformable barrier to further increase the proximity to road accidents of this offset crash. It should simulate the yielding structure involved in a car-to-car crash but at the same time with better efficiency and higher reproducibility. Based on extensive research Mercedes-Benz has defined such a realistic test. Since the deformable element according to Federal Motor Vehicle Safety Standard (FMVSS) 214 is well known and validated, it was chosen for this purpose. The force/deflection characteristics of the Honeycomb element represent the stiffness of the front end of a medium to large car. First results show that the vehicle deformation patterns are very similar to those found in real-world accidents. Another, also very important result is that the degree of overlap does not significantly influence the load on the occupants, in contrast to the tests against a rigid offset barrier.
