摘要
利用有限元分析法对发动机钠冷组合式活塞的温度场和热应力场作了分析计算，获得了活塞内部任意点的温度、位移和应力值等数据，这对评价组合式活塞的热负荷、热强度及指导组合式活塞和单材质活塞设计具有重要意义。
Making use of finite element method, the paper analyses and calculates temperature and thermal-stress field in sodium cooled combined piston of engine, obtains temperature,displacement and stress etc. data of piston inner any point, which has important significance to evaluate the thermal Ioad and strength of combined piston and direct design of combined and single material piston.
