3D Thermal Analysis of Piston in Internal-combustion Engine

This paper presents the calculation principle of the temperature, thermal deformation and thermal stress of the piston in internal-combustion engine, and calculates the temperature, thermal deformation and thermal stress of the piston by the method of finite element analysis. This paper also builds up the finite element model and boundary condition for three dimension thermal analysis, and gives the calculating results and conclusion about the design of piston.
