摘　　要：采用瑞利法及胡克定律计算安全阀弹簧的固有频率值,再通过建立安全阀弹簧模型,应用ANSYS进行有限元仿真分析,模拟安全阀弹簧在整个振动过程中的固有频率数值。通过对比计算与仿真分析的结果,最终确定仿真分析结果的偏差值,从而指导安全阀弹簧的设计与优化。The Rayleigh law and Hooke＇s law is used to calculate natural ferquencyvalue, then ANSYS is appliedfor finite element analysis bybuilding safety valve spring, model and the natural frequency valuesimulationof safety valve springin the whole process of vibration is performed. By comparing the calculation and simulation analysis re- suits, the variation valuesfrom the simulation analysis resultsarefinallyconfirmed, so as to guide the design and opti- mization of safety valve spring.
