摘要： 为了实现单柱型浮式风力机在中等深度海域的实际规模应用，以新型6 MW单柱型浮式风力机为研究对象，在极限海况下对风力机的生存能力进行模型试验和数值模拟．模型试验采用缩尺比为1∶65.3的模型在上海交通大学海洋工程国家重点实验室进行，得到风力机的六自由度运动响应、锚泊系统的受力情况以及危险受力点的受力情况．通过数值模拟软件对风力机的时域耦合运动响应进行了仿真计算．对数值模拟和模型试验的数据进行时域和频域分析，结果表明：数值模拟与模型试验结果最大偏差小于12%，吻合良好；风力机运功响应的能量主要集中在低频和波浪频率处；整个浮式风力机系统在极限海况下可可靠生存．通过数据分析对风力机的载荷极限状态进行了预报，为结构强度计算提供必要的理论依据和计算参数．

Abstract: To realize the practical scale application of the spar-type floating offshore wind turbine (FOWT) in the medium depth sea areas, a novel 6 MW spar-type floating offshore wind turbine is analyzed by model test and numerical simulation under extreme conditions. The response of main freedom degrees, the mooring tense and the stress at the danger point are explored by a 1∶65.3 scale model at the State Key Laboratory of Ocean Engineering in Shanghai JiaoTong University. Coupled motion response of the spar-type floating wind turbine is calculated by using numerical simulation software in time domain. The results of the numerical simulation and model test are compared and analyzed in time and frequency domain. The maximum deviation between numerical simulation and model test is less than 12%, which shows that the numerical simulation results are in good agreement with the model test results. The dynamic response energy of the FOWT is mainly concentrated at low frequency and wave frequency. Moreover, the whole FOWT system has an excellent survivability under extreme conditions. Finally, the ultimate load of the wind turbine is predicted, which provides the necessary theoretical basis and calculation parameters for the structural strength calculation.
Key words: floating offshore wind turbine, model test, numerical simulation, coupled dynamic response, prediction of ultimate load
