| 摘 要： | 事故再现技术是鉴定事故责任和分析事故原因的方法之一。通过对国内外车辆碰撞事故再现技术的回顾，总结了车辆碰撞交通事故再现技术的一般仿真算法计算流程，探讨了事故再现技术中影响仿真速度和精度的主要原因，其中估计车辆的初始碰撞位置参数进行迭代计算将导致较长的计算时间，忽略车辆的塑性变形和驾驶员的操纵行为将导致模型的不精确。展望了事故再现技术的发展趋势，未来的交通事故再现技术将能够推断驾驶员的操纵行为，模拟出驾驶员的生理心理变化，并能进行事故预防分析。

| Abstract: | Accident reconstruction is a method to identify the liability and analyze the cause.The research on the traffic accident reconstruction is reviewed and the typical simulation methods are analyzed.The major factors affecting the computation speed and precision are discussed.The iterative computation using the vehicle initial collision position parameters needs long time,and without considering the plastic deformation and the handling behavior of driver makes the model imprecise.The development trend of the accident reconstruction is pointed out.The future accident reconstruction can be used to deduce driver's behavior and simulate their physiological and psychological changes,and analyze the prevention of accident. |
