摘要： 目的运用计算机仿真技术模拟汽车碰撞过程,为法医学鉴定及交通事故处理提供参考依据。方法通过对汽车碰撞中乘员损伤成因分析及车辆痕迹检验,建立有效的人体、车辆仿真模型,利用动量冲量法与多刚体动力学结合仿真求解乘员运动模式,客观再现乘员交通伤特点。结果计算机仿真汽车碰撞过程中,人体模型上碰撞部位的分布符合法医学检验所得结果。结论计算机仿真求解乘员交通伤的方法在法医学鉴定和事故责任认定中具有参考价值。

Abstract: Objective To reconstruct the course of vehicle collision, so that to provide the reference for forensic identification and disposal of traffic accidents. Methods Through analyzing evidences left both on passengers and vehicles, technique of momentum impulse combined with multi-dynamics was applied to simulate the motion and injury of passengers as well as the track of vehicles. Results Model of computer stimulation perfectly reconstructed phases of the traffic collision, which coincide with details found by forensic investigation. Conclusion Computer stimulation is helpful and feasible for forensic identification in traffic accidents.
