基金信息工程和物理科学研究理事会，授权/奖励编号：EP/R 015120/1摘要我们建议通过结合双向调谐液柱阻尼器（BTLCD）和调谐质量阻尼器（TMD）的优点来减轻浮式静压风力涡轮机（HWT）的驳船俯仰和横摇运动。这是通过使BTLCD的容器能够自由移动来实现的，通过弹簧和阻尼器将其连接到主结构，从而形成我们所说的双向调谐液柱质量阻尼器（BTLCMD）。BTLCMD由HWT的液压储液器制成，通过避免添加额外的质量和流体来节省成本。HWT仿真模型是通过将NREL 5 MW驳船风力涡轮机模型的齿轮传动系统替换为静液压传动系统而获得的。然后将BTLCMD的动态并入HWT。两个简化的数学模型，描述驳船的纵摇和横摇运动的HWT-BTLCMD耦合系统，被用来获得最佳参数的BTLCMD。仿真结果表明，BTLCMD是非常有效的，在减轻驳船纵摇运动，驳船横摇运动，和塔基载荷。在抑制驳船运动方面，BTLCMD也大大优于BTLCD。
Funding information Engineering and Physical Sciences Research Council, Grant/Award Number: EP/R015120/1 Abstract We propose to mitigate the barge pitch and roll motions of floating hydrostatic wind turbine (HWT) by combining the advantages of the bidirectional tuned liquid column damper (BTLCD) and the tuned mass damper (TMD). This is achieved by enabling the container of the BTLCD to move freely, connecting it to the main structure through springs and dampers, creating what we call a bidirectional tuned liquid column mass damper (BTLCMD). The BTLCMD is made by the hydraulic reservoir of the HWT, saving costs by avoiding the addition of extra mass and fluids. The HWT simulation model is obtained by replacing the geared drivetrain of the NREL 5-MW barge wind turbine model with a hydrostatic transmission drivetrain. The dynamics of the BTLCMD are then incorporated into the HWT. Two simplified mathematical models, describing the barge pitch and roll motions of the HWT-BTLCMD coupled system, are used to obtain the optimal parameters of the BTLCMD. Simulation results demonstrate that the BTLCMD is very effective in mitigating the barge pitch motion, barge roll motion, and the tower base load. The BTLCMD also largely outperforms the BTLCD in suppressing barge motions.
