中文摘要：
基于多刚体动力学计算方法,通过对一起真实汽车碰撞自行车事故的仿真再现验证了模型的正确性,研究了碰撞后自行车骑车人的动态响应和身体损伤。然后分析比较了汽车对自行车不同碰撞速度下,骑车人的动态响应和损伤差别,模拟结果表明碰撞车速高低会影响骑车人身体部位与汽车的碰撞点位置及人体受到伤害的严重程度,以此可为鉴定类似碰撞事故起辅助参考作用。
英文摘要：
By using multi-body dynamics computing method to reconstruct an actual collision accident between vehicle and bicycle, the validity of simulation models was confirmed, and dynamic response and injuries of bicyclist in the collision course were studied. Then the collision courses under different impact speed of vehicle were simulated, and contrasts of dynamic response and injuries of bicyclist were analyzed. The simulation results showed that different impact speed of vehicle should influence the impact position that bicyclist struck vehicle, and it could provide assistant references for identification of this kind of accident.
