Fatigue life study of milled surfaces based on stress concentration factor
Abstract This paper adopts the method of combining theoretical modeling, experimental detection analysis and finite element simulation. The improved stress concentration factor solution equation is derived, and the fatigue life prediction model of plane milling surface is established accordingly. The fatigue life simulation analysis method based on surface stress concentration factor is used to obtain the influence law of surface morphology of typical parts on fatigue life, verify the accuracy of fatigue life prediction model, and provide an effective means for the analysis and prediction of fatigue performance of milling surface.
