Fretting Fatigue Life of connecting rod under multi-axial variable amplitude Stress
Abstract
Summary:A fatigue life calculation model for multi-axial variable-amplitude fatigue stress is proposed.ParisThe fatigue crack propagation rate formula is suitable for multi-axial variable amplitude stress.ParisThe life-span calculation model is obtained by introducing the modified short crack size into the formula, the life of the dangerous nodes on the mating surface is calculated. The results show that the model can be used to calculate the life of structural surface cracks from any initial size to any design size under complex conditions, which is of great significance to guide the life design of key components and to determine the maintenance time.
