    摘要:

    为探究新型漂浮式风机在不同风、浪、流载荷下对一体化拖航作业过程中风机运动稳定性能的影响。该研究基于数值仿真模拟,采用AQWA软件系统地模拟漂浮式风机在不同风载荷(风速Vwind=0、10.7、21.4 m/s),不同波浪载荷(有义波高Hs=0、1.5、2.5、3.5、4.5、5.5 m),不同海流荷载(海流流速Vcurrent=0、0.25、0.5 m/s)工况下,风浪流复杂环境对新型漂浮式风机一体化拖航运动响应的影响,并以一体化拖航过程中垂荡、横摇、纵摇及拖缆力的时历曲线以及统计特性作为主要性能指标。结果表明:在静水条件下,风荷载对漂浮式风机拖航阻力的影响较大,风速越大,拖缆力越大,平均横摇倾角和纵摇倾角越大;在相同的风荷载和流荷载情况下,随着有义波高的增加,漂浮式风机拖航阻力越大,拖航过程中漂浮式风机横摇角、纵摇角波动范围有所增大,当有义波高为5.5m时,横摇角最大幅值为1.883°,纵摇角最大幅值为5.814°;在相同风荷载和波浪荷载环境下,漂浮式风机拖航阻力随着海流流速的增加而增大,漂浮式风机纵摇角的幅值在±2.0°内波动。研究结果可为解决浮式风机拖航运输的安全问题提供参考,完善工程实践中拖航出发环境的选择。

    Abstract:

    To investigate the impact of different wind, wave, and current loads on the motion stability performance of a new type of floating wind turbine during integrated towing operations, this study is based on numerical simulations using the AQWA software. The simulations systematically model the floating wind turbine's motion response under varying wind loads (wind speeds of Vwind = 0, 10.7, 21.4 m/s), wave loads (significant wave heights of Hs = 0, 1.5, 2.5, 3.5, 4.5, 5.5 m), and current loads (current speeds of Vcurrent = 0, 0.25, 0.5 m/s). The primary performance indicators include the time history curves and statistical characteristics of heave, roll, pitch, and towing cable forces during the towing process.The results indicate that under static water conditions, wind load significantly affects the towing resistance of the floating wind turbine; as wind speed increases, the towing cable force increases, leading to greater average roll and pitch angles. Under the same wind and current loads, as the significant wave height increases, the towing resistance of the floating wind turbine also increases, and the fluctuations in roll and pitch angles during towing become more pronounced. When the significant wave height reaches 5.5 m, the maximum roll angle is 1.883°, and the maximum pitch angle is 5.814°. In the same wind and wave load environments, the towing resistance of the floating wind turbine increases with the rise in current speed, while the pitch angle remains within ±2.0° fluctuations. The findings of this study can provide references for addressing the safety issues associated with the towing transportation of floating wind turbines and improve the selection of towing departure conditions in engineering practice.
