摘　　要：依据西南某低水头水电站混流式水轮发电机组增效扩容改造项目,对新水轮机转轮进行数值模拟,采用单向流固耦合方法,研究转轮叶片在拟定水头下,导叶开度从17°~33°运行工况时的静力特性。结果表明在不同工况下该转轮叶片最大静应力与开度关系变化趋势基本一致。Based on the expansion and renovation project of low head Francis turbine in a hydropower station in southwest China,the new turbine runner is numerically simulated. The static characteristic of runner blades under guide vane opening of 17°- 33°and proposed head are studied by adopting the method of uniflow solid coupling. The results show that the relationship between runner maximum static stress and guide vane opening is basically identical under different operation conditions.
