【摘要】 [目的]为研究半潜浮式风机平台俯仰运动对平台的疲劳载荷和气动性能的影响，并探讨多液柱调谐阻尼器（TLMCD）对平台运动的抑制效果，[方法]以OC4 DeepCWind半潜浮式平台为例，开展TLMCD对浮式风机平台运动的抑制作用研究。基于该平台的结构和系泊特点设计3种不同规格的TLMCD，并利用聚焦波模型模拟真实海况中的波浪载荷，在保持原缆索系泊方式不变的情况下，分析TLMCD的调谐频率及其对平台运动响应的影响。[结果]结果表明：TLMCD对平台纵摇运动有显著的抑制效果，尤其是在平台固有频率、波浪谱峰频率和TLMCD调谐频率三者吻合条件下，调谐效率最佳。[结论]研究成果可为半潜浮式平台的运动控制设计和优化提供一定参考。更多还原

【Abstract】 [Purpose] To investigate the effect of pitch motion on the fatigue load and aerodynamic performance of a semi-submersible floating wind turbine platform, and to explore the suppression effect of tuned liquid multi-column damper(TLMCD) on platform motion, [Method] taking the OC4 DeepCWind semi-submersible floating platform as an example, the suppression effect of TLMCD on the motion of the floating wind turbine platform is studied. Three different specifications of TLMCD are designed based on the structure and mooring characteristics of the platform. The wave loads in real sea conditions are simulated using a focused wave model, and the tuning frequency of TLMCD and its impact on platform motion response are analyzed while keeping the original cable mooring method unchanged. [Result] The results indicate that TLMCD has a significant inhibitory effect on the pitch motion of the platform, especially under the condition that the natural frequency of the platform, the peak frequency of the wave spectrum, and the tuning frequency of TLMCD coincide, the tuning efficiency is the best. [Conclusion] The research results can provide some references for the motion control design and optimization of semi-submersible floating platforms.更多还原
