摘要
为研究螺旋侧板对漂浮式风力机动态响应的影响,建立基于Spar平台的5 MW风力机整机模型,利用有限元软件进行水动力计算,得到风力机平台在风浪流载荷联合作用下的时域和频域特性,通过与不附加螺旋侧板情况下的动态特性参数对比,探讨螺旋侧板能否对结构的运动性起到提升作用。结果表明:附加螺旋侧板后,结构的垂荡和纵摇的运动幅值和所受波浪力均得到显著抑制;与纵荡和纵摇相比,垂荡运动的幅值和所受波浪力均受到较大影响;螺旋侧板对缆索张力无明显抑制作用。
The whole machine models for Spar platform supported floating offshore wind turbine （FOWT） were built to research the influence of helical strake on dynamic response. In order to research whether helical strake can improve the performance of FOWT, time-domain and frequency-domain performances were gained to compare the structure with helical strake and the normal structure. The results showed that the amplitude and wave force components of FOWT with helical strake are effectively suppressed. In addition, wave forces of heave motion are more apparently influenced by helical strake than surge and pitch motion. But helical strake doesn＇ t show improvements to the cable tension of mooring cables.
