摘　　要：提出漂浮式风力机Spar平台安装螺旋布置扰流片的设计方法,通过对水动力学软件AQWA的二次开发,实现风波作用下浮式风力机动态响应的求解,对比研究扰流片螺旋布置高度对漂浮式风力机Spar平台动态响应的影响以及对扰流片平台安装系泊配重后对平台动态响应与系泊张力的影响。结果表明:扰流片平台的辐射阻尼较原平台在纵荡、垂荡、纵摇方向上均有所提升;扰流片平台的纵荡、垂荡、纵摇幅值响应算子较原平台均有所降低;随扰流片布置高度提升对平台纵摇方向运动响应抑制效果最好、垂荡方向次之。在风波耦合作用下,扰流片能够降低平台纵荡、纵摇响应,一定程度上抑制垂荡运动响应;安装扰流片可降低风力机转子推力、平台系泊张力有所上升;对系泊安装配重浮筒,在有效降低系泊张力的同时能够抑制平台纵荡、垂荡运动响应,对纵摇运动影响较小。The design method for equipping the helical spoiler plates on the Spar platform of a floating wind turbine was proposed.The hydrodynamic software AQWA was secondarily developed with FORTRAN programming.The effect of the spoiler spiral arrangement height on the dynamic response of the floating wind turbine Spar platform and the effect of installing mooring buoy on the spoiler platform on the dynamic response and mooring tension of the platform were comparatively analysed.The results show that the radiation damping of the spoiler platform is improved in the direction of surge,heave and pitch,and the surge,heave and pitch response amplitude operators of the spoiler platform are reduced compared with the original platform.Under the coupling action of wind and wave,the spoiler can reduce the surge and pitch responses of the platform and suppress the heave response to some extent.Installation of the spoiler can reduce the rotor thrust,and the platform mooring tension is somewhat increased.The mooring installation of mooring buoy float can effectively reduce the mooring tension and at the same time suppress the platform surge,heave motion responses,while the pitch motion is less affected.
