| 摘 要： | 根据水轮机叶片设计方程，对水轮机叶片曲面进行了拟合。基于PRO／MECHANICA模块对叶片结构进行了分析，对叶片的应力、应变、模态及动态时域分析后表明，水轮机叶片应力集中点可以显著确定，可在结构上采取相应措施，降低叶片应力集中。该分析方法对叶片结构设计有实用意义。

| Abstract: | According to the designing equation for blade of hydraulic turbine, a shape adaptation was carried out on the blade quilt surface of hydraulic turbine. Based on the module of Pro/MECHANICA, the structure analysis to the blade was carried out. After stress, strain, modal and dynamic time analysis on the blade were completed, the stress concentration points to the blade of hydraulic turbine can be detected obviously. Accordingly the effect of stress concentration to the blade can be on decrease of stress level by mending the structure. The analysis method is of practical ways for the blade structure designing. |
