摘要

为了获得碰撞后车辆参数和乘员损伤信息的准确性,降低样车碰撞试验的高成本和碰撞过程中的不确定因素,利用交通事故重构软件PC-Crash平台建立刚体模型和多刚体模型。设置模型的参数和初始运动状态,对交通事故碰撞进行仿真与重构,可获得碰撞车辆和乘员的瞬时运动状态参数。对交通事故的过程进行仿真演示,将演示结果与实际交通事故进行对比,真实运动模式的减少率达到95%以上,从而验证了该方法的有效性。为更好地利用PC-Crash软件实现乘员额部损伤的仿真分析提供参考,为事故处理提供理论依据。

Simulation analysis of occupant frontal collision damage*
In order to obtain the accuracy of vehicle parameters and occupant injury information after collision, and reduce the high cost of the sample vehicle crash test and the uncertain factors in the collision process, build rigid body model and multi-rigid body model by PC-Crash platform of traffic accident reconstruction software. Set the parameters and initial motion state of the model, and carry out the simulation and reconstruction of the traffic accident collision, which can obtain instantaneous motion state parameters of the collision vehicle and occupant. To simulate and demonstrate the process of the traffic accident, comparing the demonstration results with the actual traffic accidents, and the reduction rate of the real motion pattern is more than 95%,so that the effectiveness of this method is verified. It provides a reference for the better use of PC-Crash software to realize the simulation analysis of occupant's frontal injury, and provides a theoretical basis for accident treatment.
