Fatigue Strength& Analysis of Diesel Engine Piston on Finite Element Analysis

Abstract:

In this work, the variational trend of the stresses for the diesel engine piston under the operation conditions is analyzed by using finite element method (FEM) and the fatigue strength of the diesel engine piston is evaluated. The muhiaxial stress was converted into the uniaxial stress with the maximum principal stress method, and the material curve is amended by Goodman’s amendment. Finally the fatigue life and the fatigue safety factor of the diesel engine piston is obtained, which provides a better reference for structural improvements and optimization for the design of the piston.
