摘要:采用有限元软件ANSYS,分析了30/38柴油机活塞的温度场、热应力及热变形;并通过热-机耦合的方法,分析了该机活塞的耦合应力场。研究结果表明:活塞顶部应力以热应力为主,温度对活塞的应力和变形起主导作用。在此基础上提出了有关活塞的研制建议。 |

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. |
Key words: diesel engine piston thermal stress coupling finite element analysis |
