摘　　要：基于多刚体动力学仿真分析软件PC-Crash,建立车-人碰撞事故的再现模型,分别对同一工况下汽车有无ABS刹车防抱死制动系统、不同碰撞初速度以及利用随机函数确定汽车与行人的随机参数,进行大量的数字化仿真试验,分析事故发生后人体头部重要器官与车体前部碰撞点以及损伤程度的分布规律。根据分析结果,从汽车生产厂商保护行人的角度改善车身布置结构,提出有价值的参考意见。Based on the rigid body dynamics simulation analysis software PC-Crash,a vehicle-pedestrian collision accident reconstruction model is established. In the same conditions,vehicles whether anti-lock braking system or not, different initial collision speed and the use of random function determining the random parameters of the vehicle and pedestrian are simulated by experiments, the distribution of the body＇s vital organs the head and the front vehicle collision and injury severity after the accident is analyzed. According to the analysis results,valuable suggestions of vehicle arrangement structure are put forward from the angle of the automobile manufacturer for pedestrian protection.
