轿车-行人碰撞事故三维仿真再现研究

Based on multi-body dynamics method and pedestrian injury analysis, this paper established the multi-body collision models of the car, pedestrian and road and reconstructed the collision course of a real car-pedestrian collision accident on 3-D view and analyzed the dynamic response and injuries of pedestrian in the course of collision. The reconstructed results accorded with the actual accident situation. The results of injury analysis inosculated with the forensic medical identification of pedestrian body. They effectively proved the validity of methods and models. It could shorten the time to reappear accidents by 3-D simulation and reconstruction, and then improved the efficiencies of traffic management departments when they authenticate traffic accidents.
