Abstract

The embodiment of the present disclosure discloses a method for analyzing the fatigue life of a spring. The method includes: establishing a stress-cumulative action number curve; obtaining a stress-life curve of the spring material to be tested; and obtaining each of the cumulative actions according to the stress-life curve Standard stress data corresponding to the number of times; establish the stress correspondence relationship between the standard stress data and the test stress data; obtain the ultimate stress corresponding to the ultimate life of the spring material to be tested on the stress-life curve; based on the stress correspondence, obtain the limit The limit test stress corresponding to the stress; based on the limit test stress and the stress-cumulative action times curve, predict the limit test life, and use the limit test life as the fatigue life of the spring to be tested. The technical solution can truly reflect the fatigue life of the spring in the actual use environment, so that the engineering personnel can learn the potential safety hazards in time and avoid equipment damage.

Description

technical field [0001] The present disclosure relates to the technical field of fatigue life analysis, in particular to an analysis method for spring fatigue life. Background technique [0002] The spring is a basic component with buffering and shock absorbing functions, and its quality affects the operation safety of the equipment. The fatigue life analysis of the spring can provide reference indicators for the normal operation of the equipment and avoid potential safety hazards. The essence of spring fatigue life analysis is to determine the fatigue life curve of the spring material. On the fatigue life curve, the smaller the stress, the longer the fatigue life. The determination of the material fatigue life curve in the prior art is all measured on the standard test piece, which cannot truly reflect the fatigue life of the material in the actual use environment, and cannot be directly used in engineering. Contents of the invention [0003] In order to solve the proble...
