| 摘 要： | 为了对汽车错位碰撞事故的仿真再现分析提供理论算法,在分析传统一维碰撞动力学模型的基础上,总结了其应用局限性.利用经典力学原理,构建了汽车错位碰撞动力学模型与运动轨迹模型.以实际事故案例为对象,分别利用上述模型与PC-Crash软件进行案例分析.将二者的再现分析结果进行了比较,同时与事故现场车辆残留痕迹进行了对比.对比分析结果表明,再现得到的汽车转动轨迹与现场痕迹一致,模型适用于小偏心错位碰撞的事故类型.

| Abstract: | In order to provide a theoretical algorithm for simulation and reconstruction analysis of vehicle offset collision accidents,the application limitation of traditional one-dimensional collision dynamic model was summarized.Using the principles of classical mechanics,the collision dynamics model and movement trajectory model of automobile offset collision were constructed,and a real accident case was analyzed using the model and PC-Crash software.The comparative study between the reconstruction analysis results and the remained vehicle traces in the accident scene was conducted.The comparative analysis show that the turning trajectories of automobiles are consistent with the trajectories remained in the accident scene,which proves that the model is suitable for small eccentric offset collision accidents. |
