STRESS ANALYSIS AND FATIGUE TESTING OF A HERMETIC COMPRESSOR SUSPENSION SPRING

摘要

This paper describes the use of high-speed motion photography and experimental strain measurements to describe the performance of helical compression-type suspension springs during the stopping motion of a hermetic refrigerator compressor. Operating stress ranges were used to relate accelerated life test loading to service loading and to appraise the quality of the springs in relation to expected fatigue behavior. The feasibility evaluation, and confirmation of performance by experimental strain measurements, of a spring fatigue test is described.
