In order to study the vibration and wave response of the floating tidal power generation device based on the vertical axis turbine, test model and device is designed to finish the hydrostatic towage experiment and wave test with the turbine rotating and holding still, and measure the tension of the mooring chain and pitching response of the model. The experiment finds that the mooring system has a high frequency vibration phenomenon and has obvious slow shake phenomenon when V is 0.7m/s and 0.9m/s with the turbine holding still and when V is 0.9m/s with the turbine rotating. The turbine rotation also causes low frequency response of mooring chain tension. The rotation of the turbine increases not only the pitching period of the mooring system but also the resonance wavelength of the carrier model. Compared with the turbine holding still, the turbine rotation reduces the pitching response of the carrier model under low proportion of wavelength to carrier model length, while it has little influence on that under high proportion of wavelength to carrier model length. Experimental research can provide reference for theory research and engineering application of the floating tidal power generation device based on the vertical axis turbine.
