ZZ580-LH-340型水轮机顶盖结构分析及优化设计

Structural Analysis and Optimum Design for the Head Cover of ZZ580-LH-340 Hydroturbine

对ZZ580-LH-340型水轮机顶盖结构在两种工况下的应力分布和轴向变形进行分析,建立优化设计模型并得出优化结果.

The structural analysis of an existed hydroturbine head cover under two load cases are presented in the paper,leading to stress distribution and deformation state. Based on the analysis results,an optimum design method is introduced so as to reduce the weight of the head cover.
