摘　　要：通过某款车型的有限元模型分析了未安装后防撞、采用普通高强板后防撞梁以及采用超高强度板后防撞梁对于后碰时车尾部变形以及车内乘员伤害值的影响。结果表明:采取高强度的后防撞梁能减少车辆后碰时变形压缩量,降低车内乘员的伤害值。This paper analyzed the effects of no rear bumper, high-strength bumper and ultra-high- strength bumper on the deformation of the vehicle and passenger＇ s injury by using a finite element model. Results show that the rear bumper with high-strength bumper can reduce the deformation of the vehicle and passenger＇s injury.
