| 摘 要： | 为进一步提高人车碰撞再现的逼真度,研究碰撞前行人初始状态及相应的仿真实现方法,提出一种基于行走的行人假人的事故再现方法.该方法利用行人多刚体仿真模型,计算行人行走过程的动态响应,并以此确定事故再现所需的行人姿态、速度等参数.通过对一起真实事故的研究,应用不同的行人初始状态确定方法进行人车碰撞仿真,分析了不同方法对再现结果的影响.

| Abstract: | In order to improve the reality of pedestrian traffic accident reconstruction,pre-impact initial state of pedestrian was researched and the simulation method of walking dummy was presented.Based on this method,the dynamic response of walking human was modeled using multi-body dynamics method and used as the initial simulation condition for accident reconstruction.In a real-world accident case,several methods of determining pre-impact state of pedestrian were used to simulate the collision between pedestrian and bus.The influence of pedestrian's pre-impact state was analyzed in terms of the results of different methods. |
