摘　　要：为了分析不同计算手段得到的碟形弹簧载荷特性之间的差异以及摩擦系数等因素对载荷特性的影响,本文借助有限元手段对某发动机用碟形弹簧进行了弹性和弹塑性仿真计算,并与GB/T1972推荐公式解进行了对比,通过对不同摩擦系数下的碟簧组合的仿真分析,研究了摩擦系数对碟簧组合特性的影响,得出结论,为发动机的设计提供了重要的参考依据。In order to analyze the difference between the characteristics of the disc spring obtained by different calculation methods, and analyze the influence of the friction coefficient on the characteristics, the elastic and elastoplastic finite element simulation of the disc spring was carried out, and the finite element results were compared with the GB/T1972 recommended formula solution. Through the simulation of the disc spring with different friction coefficients, the influence of the friction coefficient on the disc spring characteristics was studied, and some useful conclusions are summarized, which provide an important reference for the design of the liquid rocket engine.
