摘要：

In this paper, used the Francis turbine runner blades of a hydropower station in Southwest China as the research object the computational domain was defined from the spiral case inlet to the runner export, and modal analysis on the blades was developed in the computational domain the nature frequency and vibration of the blades were got this provided theoretical support for the anti-coupling design. Abstract the hydraulic thrust using the cosine relation expressed approximately the effect of hydraulic thrust on the blades the hydraulic turbine blades in the whole computational domain regarded as a linear system and the dynamic response of the blades was got through harmonic analysis on the blades, provide the theory basis for the design of blade.
