Vibration Models of the Cross-flow Vertical Hydraulic Turbine for Free Flow

Abstract

It is urgent for us to develop hydropower resources of the rivers flowing naturally. In view of the present situation of the low efficiency transformation ,the cross-flow vertical hydraulic turbine for free flow is presented with its advantages of simple ,high-reliability and environmentally benign energy technologies. The conversion efficiency is improved effectively by the design of the water guide mechanism and governor. The strength and vibration models of the turbine are made based on finite element method. Its market prospect is very broad, and the economic and social benefit is remarkable.
