摘　　要：为了研究前排座椅参数对后排乘员在正面碰撞时的安全性影响,使用碰撞软件MADYMO建立包括车体、5%女性假人、安全带在内的某款轿车后排乘员正面碰撞仿真模型。通过试验样车碰撞结果与模型仿真结果的对比,验证模型有效性。在此模型基础上,分析前排座椅头枕和靠背参数对后排乘员的HIC、胸部3ms、胸部压缩量和左右大腿力的损伤值影响,得到了前排座椅参数与后排乘员伤害值的关系,提出减小后排乘员伤害的方法。In order to study the influence of front seat parameters on rear seat passenger when front crash happens, this article uses the MADYMO software to establish the rear seat passenger constraint system model which including ear bodies, safety belts and a 5% dummy for impact simulation. The simulation values are close to test ones after contrasted with the vehicle impact test. The influence of design parameters including the front seat headrest and backrest parameters on passenger HIC, T3MS, ThPC, femur force is researched by this model. The relationship between front seat parameters and passenger injury values is obtained, and the measure of reducing the passenger injury values is proposed.
