A STUDY ON FATIGUE AND DAMAGE MECHANICS OF PISTON

摘要：

The 1/2 rational 3-dimensional solid model of a piston is introduced to the powerful FEA software ANSYS 8.1 to analyze the thermal and mechanical coupling stress field of the piston. A special method is used to plot girding to a local model and the stress intensity factors (SIF values) of the crack original position of the piston pin seat are calculated. The results show that thermal loads have little effects on stress intensity factors, whereas mechanical loads are the dominant factors. This work can afford a theoretical foundation for the fatigue and reliability analyses of pistons.
