Finite Element Analysis for the Temperature and Stress Fields of the Diesel Piston Based on CAE

Abstract:

Adopting the finite element software ANSYS, this paper calculates the temperature and stress fields of the combined piston under the conditions of cooling and no cooling. The analytical results show that the piston under no cooling condition has higher thermal load and integrative stress than the condition of cooling, because the piston head can’t get better cooling. Moreover, the high thermal load causes the piston head creating great deformation, which has exceeded the normal gap between the piston and the liner, so the piston abrasion may worsen.
