全耦合气动-水动-伺服-弹性模型的实现，对于浮式风机设计过程中获取可靠的动态响应数值预测至关重要。本文选取偏置立柱式平台支撑结构和DTU 10 MW风机，采用AQWA和FAST软件进行联合数值模拟，系统分析附加质量、一阶波浪力传递函数以及不同海况条件下的耦合动力响应。频域研究结果表明，附加质量表现为高频范围时呈现多个峰值，而在低频范围内保持相对稳定；一阶波浪力在转动自由度上表现出低频趋零特性。时域耦合分析显示，相较于无风工况，有风不规则波作用会显著增大平台运动幅度；在相同湍流风速条件下，加入更加恶劣海况条件的浪和流会进一步加剧浮式平台的偏离振荡导致运动响应幅值明显增大。
Implementation of a fully-coupled aero-hydro-servo-elastic model is crucial to producing reliable numerical predictions of dynamic responses for the design of floating offshore wind turbines. This study employs an offset column platform supporting structure and the DTU 10 MW wind turbine and conducts coupled numerical simulations using AQWA and FAST to analyze the added mass, first-order wave force transfer functions, and coupled dynamic responses under various sea states. The frequency-domain results show that the added mass exhibits multiple peaks in the high-frequency range while stabilizing to relatively constant values at low frequencies; first-order wave forces in rotational degrees of freedom approach zero in the low-frequency range. Time-domain coupled analysis demonstrates that irregular waves combined with wind significantly amplify platform motions compared to wind-free conditions; under identical mean turbulent wind speeds, the inclusion of extreme wave-current interactions exacerbates platform offset oscillations, leading to a substantial increase in motion amplitudes.
