摘要
介绍高温状态下内燃机活塞的热分析原理，利用有限元法计算活塞温度、热变形和热应力，建立活塞三维热分析有限元模型和相应热边界条件，给出了活塞温度分布、综合应力和综合变形，提出对活塞设计的合理结论。
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.
