The effect of door structure on occupant injury in side impact

Matsumoto, Hiroyuki; Tanaka, Hideaki

Employing the proposed NHTSA side impact test conditions, and utilizing MADYMO 3D computer simulation, this paper analyzes the performance of the DOT Side Impact Dummy (DOT-SID) subjected to various contact surfaces to the dummy. Based on the results, it was found that deformation characteristics, location of the door panel and the stiffness of the door have great influence on improving occupant injury indices. Simulation results are validated through the utilization of full scale crash tests as well as hyge sled tests.
