Abstract

A fretting fatigue reliability analysis method was developed.The contact area was in a multi-axial stress state under fretting conditions.The multi-axial fatigue parameter based on the critical plane was used to predict the fretting fatigue life.On the basis of calculating determinate life

the randomicity of modulus of elasticity

friction coefficient and material constant in the life model were considered

and the fretting fatigue life reliability model was obtained by Monte-Carlo simulation method along with the response surface method.Finally

the method was applied to analyze fretting fatigue life reliability of dovetail joint

proving the feasibility and validity of this method.
