Abstract：Vortex-induced vibration tidal current energy conversion is a novel device suitable for utilizing the ocean tidal current energy in low flow speed and shallow water the ocean tidal current energy resources area.In this paper,motion mechanism of the device was studied.Based on empirical fluid force decompose model,the motion equation of vortex-induced vibration and prediction model were established and verified.A mathematical coupling model of VIV was also established and an experimental model was designed based on theoretical analysis and prediction model.Flume experiment was conducted and influence of the main parameters such as flow rate and the stiffness of the springs on the VIV responses were tested.Experimental results showed that the mathematical coupling model was valid.
