Study on Alleviating Thermal Stress of Piston Head

Abstract:

In order to alleviate thermal stress of piston head, the causes of thermal stress are studied. The original piston is modified from the perspective of easing strain concentration. The thermal stress and strain fields of the original and modified pistons are analyzed with FEM. Comparison of the analysis results shows that analyzing strain concentration is an efficient way to find out the fundamental causes of high thermal stress of piston head. Thus viable approaches are proposed to solve the problem.
