摘　　要：在MADYMO中建立安全气囊的模型,并应用PSM子结构方法建立了车人的简要模型。通过计算机仿真数据与实验进行了对比,并在此基础上从气囊直径,排气孔直径,气流率三个方面对安全气囊进行了优化,使其在正面碰撞中对驾驶员的保护作用有了明显提高。The airbag model was created by MADYMO software, and the car＇ s brief model was established by PSM sub-structure method. On the basis of computer simulation data and the experimental data, the airbag was optimized from the three aspects which is the balloon diameter, the vent diameter and flow rate, the driver＇ s frontal crash protection has been significantly improved.
