Title: FATIGUE LIFE ANALYSIS OF LARGE COMBINATION FRAME
Abstract: About the fatigue failure of the large forging press frame,a foundation of calculating crack life was proposed based on equivalent stress under the composite action of tension and pressure,and the fatigue life numerical analysis was proceeded by using finite element.The fatigue life was calculated under different values of stress concentration coefficient,overload,the residual stress and the surface roughness respectively,and the corresponding sensitivity analysis was done.Through the simulation analysis,the variation tendency of fatigue life key factors is established,which provides direct basis for the fatigue life improvement.
