摘要
文章论述了活塞热分析的理论基础,建立了活塞三维有限元模型,通过理论计算某发动机活塞热边界条件,对其进行温度场分析计算,得到活塞的三维温度场分布特征,为活塞的结构改进和优化提供了依据。
The theoretical basis of the thermal analysis of piston is discussed and a 3 - dimensional finite element model is built up. The thermal field of the piston is calculated, and the 3 - dimensional thermal field distribution characteristic is got, therefore, it supports the further improvement of piston.
