摘要(Abstract)：
本文对封闭式离心泵叶轮进行了分析,通过将弧形叶片等效为盘形夹层,得出了计算封闭式叶轮的位移和应力的解析式,从而为其结构设计与强度分析提供了一种行之有效的解析方法。
In this paper, a closed impeller of the centrifugal pump is analyzed. By means of a disk sandwich equivalent to the blades, the analytic formulas are obtained for calcutating displacement and stress in the impeller, thus a effective analytic method is provided for the structural design and strength analysis of the cloesd impellers.
