摘　　要： 通过计算机仿真技术,分析深海漂浮式风力发电机组的动力学特性。首先分别建立海上浮式平台的水动力学模型和基于动态入流理论的风轮空气动力学数值模型,然后将其施加到由"风轮-机舱-塔筒-系泊系统"组成的多柔体系统动力学模型上,并由Fortran语言编程计算,将分析模型和结果导入到ADAMS进行可视化及后处理。最后,以美国NREL基本型5 MW风电机组数据为基础,对漂浮式风力机系统和近海的定桩式风力机系统进行动力学分析对比。研究结果表明:漂浮式海上风电机组在运行过程中,其浮式平台承受水动力而产生摇荡运动,气动载荷与水动力相互耦合对整机结构动力响应及功率波动有着明显影响。 Dynamics of deep-sea floating wind turbine was analyzed by the computer simulation technology.Firstly the wave dynamics model of floating platform and aerodynamics model of wind turbine based on the generalized dynamic wake（GDW） theory were established.Secondly,the force was loaded on the multi-flexible body dynamics model of wind turbine including ＂wind rotor-nacelle-tower-mooring system＂ which was established in FORTRAN.And then the whole model and results were turned into ADAMS model.Taking a 5 MW wind turbine for example,floating wind turbine system was analyzed by multi-field coupling dynamic model.The results show that during operation of the floating wind turbine,its floating platform must withstand great hydrodynamic force,and the dynamic response of the whole structure and fluctuation of power are greatly impacted by the coupling of aerodynamic and hydrodynamic loads.
