摘　　要：120紧急阀是保证货运列车紧急情况下行车安全的重要部件,采用AMESim仿真软件对其进行了仿真分析。通过对120紧急阀工作原理的分析,建立了120紧急阀在AMESim仿真环境下的仿真模型,并对其初充气、紧急灵敏度及排气性能和安定性进行了仿真分析。通过仿真结果与试验对比分析,仿真曲线与试验曲线较吻合,证明仿真模型的正确性。120 emergency valve is the important component to ensure the freight train＇ s traffic safety when emergency situation happens.AMESim was used to simulate and analyze the 120 emergency valve. Through the analysis of the operating principle of 120 emergency valve, the simulating model un- der the environment of AMESim was built. The initial charging features, emergency sensitivity and stability were simulated. The results of simulation and test were compared and analyzed, and they are in good agreement, which indicates the correctness of the simulation model.
