Abstract

Studying thermal load of the piston of a contrapositive cam engine may provide theory for strength analysis and strucure optimization in engine development and innovation.By using finite element method(FEM) we establish a thermal model,define the boundary condition and simulate the temperature field of the piston.The results show that the temperature of whole piston is overheated,so structural parameter optimization of the piston is necessary to enhance its wearing resistance.
