摘　　要：针对NREL5MW风力机设计Spar式风力机平台并采用频域分析方法对该平台的水动力性能进行分析,研究纵荡板、平台工作水深以及重心高度对其水动力性能的影响。研究表明,垂荡板可将Spar平台的垂荡响应峰值降低至无垂荡板时峰值的1/3。当水深大于设计吃水的4倍时,水深对垂荡运动影响很小,这说明Spar风力机平台适合工作在水深大于4倍平台设计吃水的海域。当加压载后,平台重心低于设计重心的距离在0!0.8倍的设计重浮心距离范围内时,Spar风力机平台实际重心位置的偏离对平台的水动力性能影响较小。分析结果将为海上浮式风力机支撑平台的设计以及水动力性能研究提供参考。In this study,a Spar-type floating platform with wind turbine was designed to support the NREL 5MW wind turbine. Besides,this platform was modeled by the SESAM software to analyze how heave-damping plate,operating ocean depth and height of center of gravity affect its hydrodynamic characteristics. Simulation results demonstrated that the heave-damping plate reduces the peak value of heave response to 1 / 3 of the corresponding value without heave-damping plate. Operating ocean depth has marginal effect on heave response when the operating ocean depth is over 4 times of the platform＇s design draft,which means that the Spar platform with floating wind turbine is suitable to work in ocean zones where the ocean depth is more than 4 times of the platform＇s design draft.The actual deviation of center of gravity has less impact on the platform＇s hydrodynamic performance when the actual center of gravity after loading is within 0 !0.8 times of the distance between the design center of gravity and the design floating center,which is lower than the design center of gravity. The results of this study provide references for the design and hydrodynamic analysis of offshore floating wind turbine support platform.
