摘　　要：针对现有漂浮式风力机在风浪作用下运动响应较大的问题,提出一种具有圆台形浮筒的新型半潜式平台。基于FAST耦合水动力、空气动力和系泊系统等物理场,同时结合水动力学软件AQWA计算的频域参数对不同风况下漂浮式风力机动力学响应进行分析,并在额定风况下与OC4-DeepCwind漂浮式风力机进行对比。分析结果表明:不同风速对漂浮式风力机的纵荡、纵摇及艏摇运动影响明显,对垂荡运动影响较小;与OC4漂浮式风力机相比,新型漂浮式风力机在各风况下纵摇、横摇响应得到明显降低,具有良好的稳定性。In order to solve the problem of large motion responses of the existing floating wind turbines under the action of wind and waves,a new type of semi-submersible platform with round table-shaped buoy is proposed.Based on FAST coupling hydrodynamics,aerodynamics and mooring system and other physical fields,combined with the frequency domain parameters calculated by hydrodynamics software AQWA,the dynamic responses of the floating wind turbine under different wind conditions are analyzed,and compared with OC4-DeepCwind floating wind turbine under rated wind condition.The analysis results show that different wind speeds have obvious influence on the surge,pitch and yaw motions of the floating wind turbine,but have little influence on the heave motion.Compared with the OC4 floating wind turbine,the pitch and roll responses of the new floating wind turbine are obviously reduced under various wind conditions,and have good stability.
