An Investigation on Piston Pin Seat Fatigue Life on the Mechanical Fatigue Experiments

Abstract:

Article Preview

Mechanical fatigue experiments are performed for piston pin seat, and the stress-strain response of the piston overall structure is analyzed by the elastic-plastic FEA. An estimated formula of the fatigue life is put forward by amending the Manson-Coffin formula on the basis of studying the fatigue behavior of piston pin seat. The Newton iterative algorithm is applied to calculate the modified formula, and the mechanical fatigue life of piston pin seat is obtained. By comparison the predicted value with the experimental results, the feasibility of estimated formula is validated.
