Abstract

This paper describes in details the FEA process of the Chaochai YC6108ZQ piston,
establishes the 3D entity model of the piston with the help of CATIA software. Then
imports the 3D model into the ANSYS software, analyses the stress and deformation of the
piston under the condition of thermal load, mechanical load and bination of thermal
and mechanical loads using 3D FEM analysis, evaluates the piston accords to the FEA
results. Finally, introduces the solution of the thermal inflation in actual engineering. The
FEA result is helpful to the design of diesel piston.

Keywords: diesel piston, mechanical load, thermal load, ANSYS, FEA, stress,
deformation
