摘要: 为确定轿车与行人事故再现系统中各参数的敏感性,从PC-Crash软件中提取9个参数,设计正交试验,运用灰色关联度分析方法,分别获得影响轿车、行人停止位置的参数敏感性排序,按是否使用敏感性排序结果,对一起真实人车碰撞事故进行2次重建,验证试验结果的可信性与可靠性。结果表明:对再现结果有显著影响的参数为轿车碰撞时车速、行人速度、碰撞时轿车方向盘转向角、碰撞时轿车行驶方向和人体与地面摩擦因数;针对性地调整这些参数,能够明显降低各参与方的最终位置误差,并提升人车事故重建速度和与实际事故的拟合度。

Abstract: In order to determine the sensitivity of each parameter in the car and pedestrian accident reconstruction system, nine parameters were extracted by PC-Crash software, and the orthogonal test was designed. The sensitivity ranking of parameters affecting the stop position of car and pedestrian was obtained by grey relational analysis, and according to whether the ranking results are used or not, a real car-pedestrian collision accident were reconstructed twice to verify the credibility and reliability of test results. The results show that parameters that have a significant impact on the reconstruction results are the vehicle speed, pedestrian speed, steering angle of car steering wheel during collision, the direction of the car in collision, and the friction coefficient between human body and the ground, and that by adjusting these parameters in a targeted manner, the final position error of each participant can be significantly reduced, and the speed of accident reconstruction and its fitting degree with the actual accident can be improved.
