摘　　要：应用MADYMO模型进行虚拟试验或数值仿真是乘员约束系统开发流程中重要的方式。为得到可靠的计算结果,必需遵循规范的验证流程。详细介绍了MADYMO正面碰撞约束系统的建立和试验验证的流程。基于验证模型,进行了试验设计、参数灵敏度分析、响应面模型分析以及优化设计。优化设计结果使乘员受重伤的概率下降4.2%。在实际的工程应用中,利用MADYMO模拟可有效匹配约束系统的设计参数,达到稳健可靠的乘员保护效果。Virtual testing or matnemancal simulation using MADYMO becomes a vital tool for occupant restraint system development. To obtain predictive crash simulations, it is very important to validate a MADYMO model according to appropriate processes. Guidelines and considerations for frontal impact restraint system modeling and validation were described in detail herein. Based on the validated model, design of experiments （DOE）, parameter sensitivity analysis, response surface model （RSM） and optimization were performed. The probability of serious injury decreases by 4.2%. In engineering applications, MADYMO simulation is efficient way to develop robust and reliable re- straint systems.
