摘要 为研究电动自行车与轿车前部不同碰撞形态对骑车人抛距的影响,从国家车辆事故深度调查体系中选出与轿车碰撞的电动自行车事故案例21起,利用PC-Crash仿真软件建立轿车与电动自行车的碰撞模型。在此基础上进行计算机模拟试验,分析了不同碰撞形态下骑车人的动态响应过程。研究车速、碰撞夹角对骑车人抛距的影响。结果表明:骑车人横向抛距随着电动自行车速度的增加而增大;骑车人相对于轿车速度方向上的横向速度分量越大,其横向抛距越大;骑车人纵向抛距随轿车速度的增加而增大,电动自行车速度和碰撞夹角对纵向抛距影响不大。 In order to study cyclists throwing distance response to a car-electric bicycle crash,elects21cases which are car-electric bicycle collision accidents from the national vehicle accident depth investigation system.Car-electric bicycle collision model by PC-Crash simulation software was build.Carried out on the basis of computer simulation,analyzes cyclists dynamic response in different forms of collision,the effects of vehicle speed,collision angle and electric bicycle speed on cyclists throwing distance were studie.Results show that lateral throwing distance of the rider increases with the increasing of the speed of the electric bicycle.The greater the lateral velocity component of the rider relativing to the car speed direction is,greater the lateral throw distance is.The longitudinal throwing of the rider increases with the increasing speed of car.Electric bicycle speed and angle is not major influencing factors.
