Motion characteristics and aero-elastic responses of floating offshore wind turbine under coupling action of waves and winds

As a complex multi degree of freedom coupling system, floating offshore wind turbine usually works in and changeable marine environment. The research often needs to consider the effect wind, wave current at same time. Under action load, will produce large motion response. Generally, surge pitch are most obvious aspects, their amplitude is also largest, large-scale platform directly affect relative velocity loaded flow. Therefore, have impact on aerodynamic load turbine. In this paper, characteristics aeroelastic responses DTU-10MW semi-floating under simulated. calculated different combination conditions, influence law summarized. results show that affects mean value turbine, motion; Finally, dynamic response with included angle discussed analyzed, incident analyzed.
