摘要
利用PC-Crash模拟高速条件下轿车与行人后部的碰撞过程，试验假人选择PC-Crash标准成年假人模型，碰撞后汽车驾驶员未采取紧急制动措施，仍然按照碰撞时刻的车速行驶，试验车速区间选择75-155km／h。研究了不同碰撞车速下行人的第一落地点和最终静止点抛距变化规律，分析了行人头部在事故中所受到的碰撞接触力的变化规律，在此基础上建立汽车-行人高速碰撞模型并进行对比验证。
A simulation test for high-speed car/pedestrian-back collision was carried out with a test speed of 75 to 155 km/h, using accident reconstruction software PC-Crash. In the test, an adult dummy was used and after collision the driver did not apply urgent braking but drove on with the test speed. The models of throw distance for both first falling spot and final settle position were established and compared with other model. The contact forces between dummy head and vehicle during collision were also analyzed.
