Abstract: The traces of falling objects in the traffic accident are very important significance to accident reconstruction analysis. The test of vehicle headlamp simulation collision has been put up on the dry the bitumen road surface in the paper. In the process authors analyzed splinter area distribution and picked up selectivity reconstruction model is founded and the feasibility and validity of model is discussed.

Key words: accident reconstruction, multivariate regression, throw distances, impact tests

摘要： 交通事故现场遗留散落物对事故再现分析有着非常重要的意义。本文在干燥沥青路面进行不同车速下的汽车前照灯模拟碰撞试验，应用VC2000PC加速度计实时测量车辆运动参数，通过分析散落物碎片分布场的形态，选择性提取前照灯碎片分布场的特征参数，构建对应事故再现模型，并对模型的有效性和可行性进行了探讨。
