| 随着海上风电场的快速发展，海上浮式风机（floating offshore wind turbine，简称FOWT）技术在深远海域应用中备受关注。为研究浮式风机张力腿平台（tension leg platform，简称TLP）在复杂海洋环境下的运动响应及水动力性能，基于势流理论和时域模拟，建立了TLP型FOWT的水动力数值模型，并深入探讨了风、浪等环境载荷对平台六自由度运动的影响。模型全面考虑了风、浪与平台结构之间的耦合效应，即风力与波浪载荷通过平台结构的传递与相互影响。结果表明，双张力腿筋腱方案相较于单张力腿筋腱方案在复杂海况下显著提高了平台的动态稳定性，有效降低了平台的运动幅值。此外，波浪入射方向对平台的波频响应影响显著，正面入射波浪激发的波频响应最强，而侧向波浪的激励效应相对较弱。在风浪联合作用下，随机风场较定常风场显著加剧了平台的低频和波频响应波动，尤其显著增大了迎风侧张力腿的瞬时张力。 |

| With the rapid development of offshore wind farms, floating offshore wind turbine (FOWT) technology has gained significant attention for applications in deep-sea regions. To investigate the motion response and hydrodynamic performance of a tension leg platform (TLP)-type FOWT under complex marine environments, a hydrodynamic numerical model is established based on potential flow theory and time-domain simulation. The study comprehensively examines the impact of environmental loads such as wind and waves on the six degrees of freedom motion of the platform. The model fully accounts for the coupling effects between wind, waves, and platform structures, considering the transmission and interaction of wind and wave loads through the platform. The results indicate that the dual-tension leg tendon configuration significantly enhances the platform's dynamic stability under complex sea conditions, effectively reducing motion amplitudes compared to the single-tension leg tendon configuration. Moreover, the wave incident direction has a pronounced effect on the platform's wave-frequency response, with head-on waves inducing the strongest wave-frequency response, whereas lateral waves exhibit weaker excitation effects. Under combined wind and wave conditions, random wind fields lead to more pronounced low-frequency and wave-frequency response fluctuations than steady wind fields, particularly increasing the instantaneous tension in the windward tension legs. |
