| Abstract: | By making use of finite element software ANSYS, the temperature field, thermal stress and thermal deformation of the 30/38 diesel engine piston were analyzed. And the coupling stress field of this piston was analyzed by the method of thermal-mechanical coupling.The results indicated that the stress on the top of the piston was mainly thermal stress,and the temperature played a leading role in the stress and deformation of the piston.On the basis of this,relevant suggestions on the development of piston were provided. |
