摘要
为提高人车碰撞事故再现仿真的准确性,分析行人的初始状态对仿真结果的影响,提出了一种以多刚体行人假人为模型的事故再现方法。该方法仿真行人行走的动态过程,从而确定事故再现中所需要的行人姿态、步速等初始状态参数。通过再现一起真实交通事故,论证了行人初始状态对事故再现结果的影响,并证明了该方法的正确性。
In order to improve the accuracy of reconstruction simulation on vehicle-pedestrian crash accident and analyze the effects of pedestrian＇s initial state on simulation results,an accident reconstruction method is proposed based on a multi-rigid-body model for walking dummy.The dynamic process of pedestrian＇s movement is simulated,and thus the initial state parameters including the gait and walking speed of pedestrian required for accident reconstruction are determined.The results of reconstruction on a real traffic accident using the method verify the influences of the initial state of pedestrian and the correctness of the method proposed.
