摘　　要：近三年来,全国交通事故的年均发生数量在20万次以上,多车碰撞事故的数量也逐年攀升。文章根据车辆碰撞时间的先后顺序将一则复杂的交通碰撞事故,等效成多个简化的碰撞事故,且每个碰撞过程只包含两个事故参与方。通过对事故现场中驾驶员进行损伤验证,以及事故车辆进行痕迹勘验,分析人体损伤程度、各个车辆的碰撞形式和碰撞前的运动速度,运用PC-Crash软件进行事故仿真并验证其真实性。结果表明,仿真得到的人体损伤情况与实际情况相符;事故参与方的最终停止位置、碰撞速度与实际勘验数据相比,误差均小于10%,说明仿真结果与实际勘验的结果相吻合。此方法对复杂的交通碰撞事故能够进行模拟,并且仿真具有一定的真实性,为交通管理部门进行事故责任认定提供了理论支撑。In the past three years,the average annual number of traffic accidents in China has been more than two hundred thousand times,and the number of multi-vehicle collision accidents has also increased year by year.This paper is based on a complex traffic collision accident,which is equivalent to multiple simplified collision accidents according to the sequence of vehicle collision time,and each collision process only contains two accident participants.By verifying the damage of the driver in the accident scene and the trace inspection of the accident vehicle,the degree of human injury,the collision form of each vehicle and the motion speed before the collision are analyzed,and the accident simulation is carried out with PC-Crash software and its authenticity is verified.The results show that the human injury condition obtained by simulation is consistent with the actual condition;Compared with the actual inspection data,the error of the final stopping position and collision velocity of the accident participant is less than 10%,indicating that the simulation results are consistent with the actual inspection results.This method can simulate the complex traffic collision accident and the simulation has a certain authenticity,which provides a theoretical support for the traffic management department to identify the accident responsibility.
