摘　　要：构建DTU 10MW风电机组全耦合非线性模型，使用开源软件FAST计算10MW风电机组在多种工况下的动力学响应，通过时频域分析和箱线图分析对漂浮式风电机组风轮的动态响应进行研究。结果表明：风轮叶片响应主要是风载荷引起；浮动平台纵荡、纵摇运动与风轮叶片运动的附加耦合作用会增大风轮推力、叶根弯矩和叶尖挠度的波动性，波浪载荷会增大风轮叶片的疲劳载荷。A fully coupled nonlinear model of a DTU 10 MW wind turbine is constructed. The open-source software FAST is used to calculate the dynamic response of a 10 MW wind turbine under various operating conditions. The dynamic response of floating wind turbines rotor was studied by time-frequency domain analysis and box-plot analysis. The results show that wind turbine blade response is mainly caused by wind load. The additional coupling between the surge, pitch motions of floating platform and the rotor blade motions of the wind turbine will increase the fluctuation of the rotor thrust, blade root bending moment and blade tip deflection. The wave load will increase the fatigue load of the wind turbine blade.
