摘　　要：根据电动自行车与轿车碰撞事故调查结果,对骑车人碰撞伤害特点和伤害原因进行了研究。在仿真计算中选用THUMS生物力学假人代表骑车人,并与真实交通事故数据进行对比,证实了本文方法的可靠性。通过对电动自行车与轿车碰撞中骑车人伤害情况的仿真分析可知,电动自行车与轿车碰撞中骑车人下肢发生严重伤害的概率远大于其他部位,在新车开发中优化发动机罩前缘的造型和结构设计能够降低骑车人下肢的伤害概率。本研究结果可为车辆安全法规制定和新车安全性能开发提供参考。Based on the data of collision accident between car and electric bicycle obtained by CIDAS, the cyclist injury mechanism and the causes are studied. The THUMS biomechanical dummy is used to represent the cyclist in the accident. Comparison of the simulation results with real accident data shows that the method is reliable. Analysis suggests that the probability of serious leg injury is higher than other body part injury in the collision accident. The structure of the frontier of the engine cabin is the key parts to reduce the leg injury. The simulation results can provide valuable reference for designing safety regulation and new car development.
