Abstract

Accident analyses show that in most of the frontal car-to-car collisions the stiffer zones such as the engine and the front end structures do not overlap, affecting the softer zones of the impacting cars. Therefore, the amount of energy absorbed in both longitudinal members is relatively low. For this reason and in order to increase the effort spent on a realistic frontal test procedure, Mercedes-Benz is extending its offset test program by a test against a deformable barrier. Since the deformable element according to FMVSS 214 is well known and validated, this Honeycomb element was chosen for this purpose. The force/deflection characteristics of this element represent the stiffness of the front end of a medium to full-size car. First, results show that the vehicle deformation patterns are very similar to those found in the course of real-world accidents. Another important result is that the degree of overlap does not greatly influence the load on the occupants. In contrast, the tests against a rigid offset barrier are very sensitive to different degrees of overlap.
