摘　　要：为探索骑乘人员的损伤差异,基于PC-Crash仿真软件,以车型、碰撞车速和碰撞形态为变量进行147组汽车碰撞载人摩托车的仿真,在此基础上用统计学方法分析所得数据。结果表明:绝大多数碰撞条件下,包括不同碰撞车速,骑车人头、胸部和撞击侧下肢损伤指标参数的均值均高于后座乘员;此外,当碰撞车速分别为45和50 km/h时,骑车人和后座乘员的头、胸部损伤都超过其安全界限。To explore the injury difference between motorcyclist and occupant,based on PC-Crash simulation software,with the vehicle type,collision speed and collision pattern as variables,a simulation on 147 sets of vehicle-manned motorcycle collisions is carried out.On this basis,the data obtained are analyzed by statistical methods.The results show that under most collision conditions including different collision speeds,the average value of injury indicators of the head,thorax and impact side lower limb of motorcyclist is higher than that of occupant.In addition,when the collision speed is 45 and 50 km/h respectively,the head and thorax injuries of both motorcyclist and occupant exceed their corresponding safety limits.
