Very-high-cycle fatigue responses of stainless steel for compressor valve plates

Abstract

Very High Cycle Fatigue (VHCF) responses of stainless steel used for air conditioning compressor valve plates under different loading conditions were investigated. Firstly, the material mechanical responses considering the specimen extracted directions were conducted and compared for predicting the fatigue life. The stress distribution in the simple specimen was examined for these specimens. Furthermore, the fatigue experiments were conducted to explore the variations in calculation methods of materials for the compressor. According to the calculated results under the static and dynamic loading conditions, the results demonstrates that the fatigue life results by the static stress approach is superior to that of the dynamic stress approach with a narrow scatter band. The computed strategy for the high cycle fatigue data could further estimate the fatigue life of structures of air conditioning compressor valve plates.
