摘要: 为研究电动二轮车侧面与运动型多功能车(SUV)前部碰撞中骑车人头部损伤,从国家车辆事故深度调查体系(NAIS)中筛选一起案例,利用MADYMO软件建立并验证SUV与电动二轮车的多刚体模型。在此基础上进行计算机仿真试验,研究不同电动二轮车车身侧倾角、SUV车速、电动二轮车车速对骑车人头部损伤的影响。结果表明:骑车人头部损伤随电动二轮车车身侧倾角的增大先增大后减小,头部初始碰撞时刻随电动二轮车车身侧倾角的增大而增大,随SUV与电动二轮车车速增大而减小。

Abstract: In order to study the cyclist's head injury when a electric bicycle's side is in collision with a SUV's front part, MADYMO software is adopted to establish and verify the multi-rigid model of the SUV and the electric bicycle through a case selected from National Automobile Accident In-depth Investigation System (NAIS). On this basis, computer simulation experiments were carried out to study the effects of the electric bicycle's roll angle, the speed of the SUV and that of the electric-bicycle on the cyclist's head injury. The results show that the cyclist's head injury increases first and then decreases with the increase of the electric-bicycle's body roll angle; it increases at the initial collision as the electric-bicycle's roll angle increases, and it would decrease with the acceleration of the SUV and the electric-bicycle's speed.

Key words: electric bicycle, sport utility vehicle (SUV), roll angle, cyclist, head injury
