Study on Loads of Accelerated Contact Fatigue Testing and its Application

Abstract:

For reducing the development time and cost, determining the load of accelerated contact fatigue testing of a multi-case and multi-stage drive train, multilevel design load method was used to calculate the pitting equivalent loads of gears according to the load spectrum. A reasonable load of pitting fatigue testing was determined after analyzing and studying the pitting equivalent loads of gears. Based on a reducer used for a cement mixer, the pitting equivalent loads of gears were calculated, and the load of pitting fatigue testing was determined. The damage ratios of gears were calculated by the pitting equivalent loads of gears and the testing load, separately, using software MASTA. The results from the load of pitting fatigue testing and the testing load were coincident.
