Abstract

Abstract

Finite element analysis method is used to solve the problem that calculation formula in spring manual is not applicable for a special ring spring in high temperature environment. This special ring spring has a single layer outer ring structure, and material of the inner ring is different from the material of the outer ring. Based on the results of finite element analysis, an improved calculation formula for ring spring design has been established.
