摘要： 系泊系统是保障浮式风电系统长期稳定运行的关键结构。近年来，为提升系泊性能，降低建造与运维成本，基于附加浮子的系泊系统优化设计方案得到了广泛关注。在系统梳理国内外相关研究基础上，针对海流作用下浮子的动态响应特性，设计并开展了基于1∶25缩尺比的浮子模型在循环水槽中的流载荷试验，测量了不同流速下浮子的纵摇角度与缆绳拉力，分析了浮子流载荷系数随流速变化的规律。试验结果表明，浮子在高流速下表现出明显的流致振动，其拉力在水平方向呈持续增长趋势，竖直方向则因振动影响产生非单调变化，所得无量纲流载荷系数范围为1.056~1.538，可为浮式风电系泊系统中浮子设计提供重要参数支撑，提升浮式风电系泊系统的安全性与经济性。

Abstract: The mooring system of floating offshore wind power structures is a key component ensuring their long-term stable operation. In recent years， to enhance mooring performance and reduce construction and maintenance costs， optimized mooring system designs incorporating auxiliary buoys have attracted widespread attention. Based on a comprehensive review of related studies both domestically and internationally， this paper focuses on the dynamic response characteristics of buoys under ocean current effects. A series of current-induced load experiments were conducted in a circulating water channel using a 1∶25 scale buoy model. The pitch angle of the buoy and the mooring line tension were measured under different current velocities， and the variation law of the current load coefficient with current velocity was analyzed. The experimental results indicate that the buoy exhibits significant current-induced vibrations at high current speeds. The mooring tension shows a continuous increase in the horizontal direction， while in the vertical direction， the tension demonstrates non-monotonic variation due to vibration effects. The obtained dimensionless current load coefficient ranges from 1.056 to 1.538. These results provide essential parameters for the design of buoys in floating wind turbine mooring systems， thereby improving their safety and cost-effectiveness.
