| 超大浮体作为一种可提供大面积海上作业空间的浮式结构物，在多用途开发领域展现出巨大潜力。然而，其大尺度结构在波浪作用下易产生水弹性变形，对结构安全性与稳定性构成威胁。铰链式波能装置为抑制超大浮体水弹性响应提供了一种潜在解决方案，而在浮体上集成风机则进一步拓展了其多功能应用场景。本文基于多体动力学和有限元方法，通过OrcaFlex构建超大型风浪联合系统时域全耦合动力模型。首先，验证所建的水弹性模型的准确性，继而针对特定模拟工况优化铰链式波能装置阻尼系数；基于此，在不规则波与湍流风复合环境下，系统分析超大浮体的水弹性响应特性、风机动力学性能及系统综合获能效率。研究结果证实，铰链式波能装置不仅能有效抑制超大浮体水弹性响应，还可与风机产生协同效应，为多能集成与结构优化提供支撑。 |

| Very large floating structures (VLFS), which provide extensive operational space at sea, offer substantial potential for multi-purpose offshore development. However, their large structural dimensions make them susceptible to hydroelastic deformation under wave action, thereby posing risks to structural safety and overall stability. Hinge-type wave energy converters (HTWECs) present a promising means of mitigating these hydroelastic responses, while integrating wind turbines on VLFS further broadens their multi-functional application prospects. Combining multi-body dynamics with the finite element method, this study develops a fully coupled time-domain model for an ultra-large hybrid wind-wave system using OrcaFlex. The accuracy of the hydroelastic model is first validated, followed by an optimization of the HTWEC damping coefficient for specified simulation conditions. On this basis, under combined irregular waves and turbulent wind fields, the hydroelastic response characteristics of the VLFS, the dynamic performance of the wind turbine, and the overall energy capture efficiency of the integrated system are comprehensively examined. The results confirm that HTWECs can effectively suppress VLFS hydroelastic responses and can also act synergistically with the wind turbine, thereby supporting multi-energy integration and structural optimization of VLFS. |
