为探寻复杂环境和多自由度耦合运动下的漂浮式风机气动载荷特性及影响规律，基于研制的新型6 MW浮式风电机组缩尺模型，采用滑移网格结合重叠网格的方法，开展不同叶尖速比下漂浮式风机气动力特性网格与时间步长收敛性以及湍流模型适用性研究，并将数值仿真结果与风洞试验测试结果进行对比，建立漂浮式风机气动力特性高保真数值仿真模拟技术。在此基础上，进一步开展漂浮式风机纵摇、横摇单自由度运动和两自由度耦合运动下的整机气动载荷特性及影响规律研究，揭示运动状态下漂浮式风机气动载荷物理特性，研究结果表明：风机纵摇、横摇两自由度耦合运动状态下，单独减小纵摇周期时，扭矩系数和推力系数最大值增大，且最小值减小，导致双幅值显著增大，而平均值几乎不变。研究结果可为漂浮式风机气动载荷特性仿真预报、气动效能评估以及风电机组风洞试验测试技术完善提供技术支撑。

To investigate the aerodynamic load characteristics and influence laws of floating offshore wind turbines (FOWTs) under complex environments and multi-degree-of-freedom (DOF) coupled motions, a study was conducted based on a scaled model of a novel 6-megawatt FOWT. A combination of sliding mesh and overlapping grid methods was employed to analyze grid and time step convergence of aerodynamic characteristics, as well as the applicability of turbulence models across various tip speed ratios. Numerical simulation results were compared with wind tunnel test outcomes to establish a high-fidelity numerical simulation technique for predicting FOWT aerodynamic characteristics. Building upon this, further research explored the aerodynamic load characteristics and influence laws of FOWTs under single-DOF motions (pitching and rolling) and coupled two-DOF motions, aiming to elucidate the physical properties of aerodynamic loads on FOWTs in dynamic states. The findings indicated that, under coupled pitching and rolling motions, a reduction in the pitching period alone increased the maximum values of torque and thrust coefficients while decreasing their minimum values, leading to a significant amplification of double amplitudes, with average values remaining relatively unchanged. This research offers technical support for the simulation prediction of aerodynamic load characteristics, the evaluation of FOWT aerodynamic performance, and the enhancement of wind tunnel testing techniques for wind turbine arrays.
