摘　　要：以某车型轿车为对象建立了整车有限元模型,在此基础上集成了包括假人和安全带的乘员约束系统有限元模型。按国家标准《正面碰撞乘员保护的设计规则》规定的试验条件,对整个集成系统进行了正面碰撞的数值模拟和分析,求解出了整车的位移、速度、加速度、能量及人体模型的伤害值,实现了对该车正面碰撞过程及碰撞性能的较全面且较可靠的评价。Take a car as an example, the complete finite element models of a passenger car and the occupant restraint system including dummy and the seatbeh subsystem, were presented. According to the CMVDR 294, the frontal crash into a rigid wall of the car at about was successfully simulated and the results include the car＇ s displacement, velocity, acceleration and the dummy＇ s injury value, achieved comprehensive and credible appraisement with the frontal crash process and crash performance.
