Simulation of car-pedestrian accident for evaluate car structure

Yoshida, Suguru<sup>1</sup>; Matsuhashi, Tetsuo<sup>1</sup>; Matsuoka, Yasuhiro<sup>2</sup>

A new computer system and human body model to simulate the pedestrian road accidents involving vehicles were developed for evaluating vehicle structure and pedestrian injury. The aim of the simulation system is to predict the dynamic behavior of pedestrians and influence of car shape and structure on the pedestrian injury. To evaluate actual vehicle shapes and structures, this system carries simulations into an FEM environment. And new types of human body models were developed for the simulation. The character of human body model is to have a self-scaling modeling program for any pedestrian weight and height and particular joint characteristics obtained by the PMHS test. This paper describes the content of the simulation system and presents some results from the simulations.
