摘　　要：根据GTR 9对某一轻型客车进行刚性腿型碰撞试验。结果表明:与胫骨接触的车辆前端结构刚度对小腿上端加速度、膝部最大动态弯曲角度、膝部最大动态剪切位移都有较大影响;通过对车辆纵梁和前横梁添加薄壁钢可有效降低行人小腿和膝部损伤。TRL impact tests are done for a light bus based on the GTR 9 assessment program. The results show that the bus front structure stiffness contacted with the impactor tibia position has a great influence on the acceleration of upper leg,the maximal dynamic bending angle and the maximal shear displacement of knee joint. By adding the thin-walled steel to the longitudinal beam and the front cross beam,the injury to the leg and knee of the pedestrian is significantly reduced.
