基于蠕变模型的波形弹簧弹力衰减特性分析及寿命预测研究
Elasticity decay characterization analysis and life prediction of wave spring based on creep model
摘要
Abstract
In a high-temperature environment,the elasticity of wave spring will be attenuated due to the spring stress relaxation and material aging,which will affect the sealing effect and even cause the sealing device to fail to operate normally.For this reason,based on the test data of wave spring elasticity decay,a numerical analysis model of wave spring elasticity decay was established by using the creep model.The influence of temperature and initial elasticity on the wave spring elasticity decay was investigated,and a prediction method for the wave spring life was proposed based on the Arrhenius model.The research results showed that the elasticity loss rate of wave spring increased significantly with the increase of temperature.The larger the initial elasticity was,the higher the elasticity loss rate was,and the elasticity decay process was divided into two stages of sharp decrease and slow decrease.The established life prediction model could accurately predict the service life of wave spring.The research results provide a basis for the reliability design and life prediction of wave spring in engineering applications.关键词
