摘　　要：针对弹用减压器的高可靠性需求,结合减压器出现的输出压力偏高、出口压力振荡等故障问题,对重要零部件如活门、弹簧、密封圈等,以减压器的使用环境条件、贮存条件以及工作载荷为基础,开展其全生命周期的复杂应力条件下的失效分析,识别其关键设计参数弹簧刚度和胶圈摩擦力及参数变化范围。根据减压器结构设计参数和进出口工作参数,采用AMESIM建立工作性能模型并通过试验验证模型的有效性。在此基础上结合失效分析数据建立减压器的多故障模式仿真模型,实现其多故障模式工作特性仿真分析,为开展减压器可靠性设计优化提供数据支撑。Focus on the high reliability requirements of bomb pressure reducer,combined with the failure problems such as high output pressure and outlet pressure oscillation,the use and storage environment conditions of important parts such as valve,spring and seal ring reviewed in the whole life cycle,failure analysis under complex stress conditions were carried out,and the key design parameters spring stiffness and rubber friction were identified.According to the design of pressure reducer structure and the inlet and outlet parameters,the working performance model is established by AMESIM,and the validity of the model is verified by experiments.On this basis,the multi-fault mode of the pressure reducer is established by combining the failure analysis data,and the dynamic simulation analysis of its multi-fault mode operating characteristics is realized,which provides data support for the reliability design optimization of the pressure reducer.
