摘　　要：为满足发动机向高功率密度(HPD)方向发展的需要,设计了一种新型全钢活塞,论述了全钢活塞传热边界条件,并借助有限元分析软件MSC.NASTRAN对其进行温度场计算,与传统铝活塞在重量上进行了对比,为全钢活塞的结构分析和改进提供了参考。In order to meet with the high power and density of engine development,a new style steel piston was set up. This paper described the heat transfer boundary conditions of steel piston and used MSC. NASTRAN software to calculate the temperature field of the steel piston. Weight of traditional aluminum piston was compared, which provided some references for the structural analysis and improvement of steel piston.
