摘要

This paper investigates the model test research of a semisubmersible floating wind turbine. An improved method is proposed to correct the deficient thrust force in a Froude-scale experimental condition, which is able to simulate the rotor operational state more realistically by allowing the rotor to rotate freely with the wind. This approach also maintains tip speed ratio to some extent and overcomes previously reported negative effects produced by common correction. ways. Reduced platform resonant motions in the presence of wind force are observed. Due to rotor rotation, resonant yaw and roll motions are induced even in heading wind and wave state. Tower vibration is found to be suppressed by the wind force. Multi-frequencies components are observed in the response of tower-top shear force, which is governed by the couplings of hydrodynamic loads, aerodynamic loads and tower vibration. It is also found that the dynamic response of the mooring line is mainly dominated by wave load and aerodynamic effect can be simplified as an extra constant force. (C) 2017 Elsevier Ltd.
