Hu Guangyun;Wang Kui;Wang Yanbing;Tu Danhong;Hu Zhuchang;China Shipbuilding Power Engineering Institute Co., Ltd;Shanghai Diesel Engine Co., Ltd;  
A type of medium-speed diesel engine piston pin was studied in this paper, the Finite Element Analysis on structural strength and fatigue properties was carried out respectively. In the analysis of fatigue properties, we acquired of nitriding case depth according to the hardness test results piston pin,proposed a way to define nitriding material, investigated varying safety factors with different nitriding case depth of piston pin.
【Key Words】: piston pin nitriding case fatigue safety factor
