中文摘要：

为准确再现车辆侧滑事故,基于Pc-Crash软件,提出一种分步再现事故的方法。该方法首先仿真事故车辆侧滑运动,获得侧滑车辆碰撞前瞬间运动状态参数;然后定义新仿真以再现侧滑车辆与事故其他参与者的碰撞;重复此2步骤,以确保仿真中痕迹与事故中痕迹最相符合。最后就一例车辆侧滑后与过往车辆发生碰撞的事故,演示该分步再现方法各步骤的实现途径。结果显示,利用Pc-Crash软件分步再现车辆侧滑事故,能较为容易地控制再现过程,保证仿真中痕迹与现实情况的一致性。

英文摘要：

In order to reconstruct vehicle sideslip accident easily and accurately, a fractional-step recon- struction method was proposed based on Pc-Crash. In the fractional-step method, the sideslip motion of the vehicle is simulated firstly, and then the impact of the sideslip vehicle with those involved in the accident will be simulated, after that, these two steps will be repeated to make simulation results accord with the true traces. Finally, a sideslip-vehicle accident was given, the steps of the new method were demonstra- ted, and results show that through the new method, traffic accidents can be easily reconstructed and the obtained results were well in accord with the true traces.
