Description
Summary:For mechanical elements subjected to the coupling damage from both contact fatigue and sliding wear, the traditional single failure criterion has significant limitations for the designs requiring high reliability and high precision. Therefore, based on the combination of analytical approach and numerical method, a novel coupling analysis method of contact fatigue damage and sliding wear damage for a typical linear contact is proposed in this paper. In this method, a reasonable model for damage correction coefficient, taking into the load, the temperature and the friction coefficient, is developed for the purpose of determining the operating stress of coupling conditions. The model of contact fatigue damage contribution rate and sliding wear damage contribution rate are proposed. Furthermore, a coupling model for contact fatigue damage and sliding wear damage is developed, and the applicable damage criterion is determined. The rationality and practicability of the coupling analysis method proposed are verified by two examples.
