为提高轿车后排乘员在发生正面碰撞时的安全性，文章利用碰撞仿真分析软件MADYMO，建立包括某轿车车体、安全带和假人的乘员约束系统正面碰撞模型，并与碰撞试验结果进行对比，验证了模型有效性。利用该模型对安全带形式和座垫角度对乘员的HIC、胸部3ms加速度和左右大腿力等损伤值的影响进行了比较，表明使用3点式安全带同时匹配座垫倾角25。的方法，能使头部损伤下降59％，胸部伤害下降20％，腿部损伤下降70％．有效提高后排乘员的安全性。

In order to improve the safety of rear occupants when front crash happens, an occupant restraint system model consisting of car bodies, safety belts and a dummy was established and its validity was verified by contrasting with the vehicle impact test based on the software MADYMO for impact simulation analysis. The effect of design parameters including belts and cushion angles on passenger injury values was researched by using this model. With the improvement of decreasing the HIC, T3ms, as well as the head injury, chest injury and leg injury by 59%, 20%, and 70% respectively, the method of using three- point seat belts and seat cushions at the angle of 25° was proposed so that the safety of the rear seat occupants can be effectively improved.
