摘　　要：半潜浮式风力机的动力响应是评价结构安全性的重要参考依据,为研究浮筒尺寸对半潜浮式风力机动力响应的影响,根据规范及经验提出适用于我国浅水海域的无撑杆半潜浮式风力机平台,该平台包括浮筒、侧立柱和三角连接构件。采用SIMA耦合分析程序,建立风力机-塔筒-平台-系泊整体耦合模型进行仿真模拟,分析浮筒尺寸对半潜浮式风力机动力特性的影响。结果表明:半潜浮式平台浮筒宽度增大,浮式风力机的固有周期呈现逐渐增大趋势,且有利于改善极端工况下半潜浮式风力机的塔基弯矩和浮式平台的纵荡和纵摇运动,但对浮式平台的系泊张力影响较小。The dynamic response of semi-submersible floating wind turbines(FOWT)is an important reference for evaluating structural safety.In order to analyze the influence of pontoon dimensions on the dynamic response of semi-submersible FOWT,the procedures for the preliminary design of braceless semi-submersible FOWT are summarized to shallow water in China referring to the offshore standards,which includes pontoons,columns,and triangular connection structures.The coupled rotor nacelle assembly-tower-floating platform-mooring system is established in simulation tool SIMA.The results show that the increased structural natural periods and improved surge and pitch motions of the semi-submersible FOWT are observed by increasing the pontoon width.In addition,the semi-submersible platform with different pontoons has a relatively small impact on the mooring line tension.
