摘　　要：应用碰撞动力学理论对小汽车与两轮车碰撞过程进行分析,分别构建了小汽车与两轮车碰撞后各自的运动轨迹模型,并运用自编软件实现车辆碰撞运动轨迹的再现仿真;选取碰撞事故案例,将求解结果与PC-Crash软件再现数据对比分析,结果表明模型可信度较高。In the car and two-wheelers collision analysis,the motion trajectory identification is the key technical difficulty.Based on dynamics analysis of car and two-wheelers collision,the motion trajectory of each was developed in this paper.The models were also programmed into a software to simulate vehicles＇ motion trajectories after collisions.At last,with one real collision as a case study,the results of motion trajectory models are compared with the simulated data from PC-Crash software.The comparison results show that the trajectory model constructed in this paper has higher accuracy.
