Considering the importance of wind turbine tower, its vibration under multi-hazard action consisting of vortex-induced load and seismic load needs to be controlled, especially as the height of the wind turbine tower increases, it increases the risk of its higher-order vibration. To address this issue, theoretical equations for vortex-induced load based on the governing equation of particle damping system are put forward, the vibration control of a 1/20 scale wind turbine model is studied, and the experimental and numerical analyses are conducted. Many studies have shown that wind turbine tower equipped with tuned mass damper (TMD) can result in an RMS response reduction ratio ranging from 20% to 40%. Compared to TMD, particle tuned mass damper (PTMD) has better vibration control effect under single seismic load, and still achieves good vibration control ability with a maximum RMS (root–mean–square) reduction ratio of 35.55% under multi-hazard action. Furthermore, MPTMD (multiple particle tuned mass damper) is proposed for controlling higher-order vibration mode, achieving a maximum RMS reduction ratio of 65.93%. Combining the spectrum diagram result, the ability to control higher-order mode vibration of MPTMD is confirmed.

地震与涡致风多重灾害作用下风电机塔PTMD振动控制效果分析

考虑到风电机组塔架的重要性,其在涡激载荷和地震载荷等多重灾害作用下的振动需要得到控制,特别是随着风电机组塔架高度的增加,其发生高阶振动的风险增大。针对这一问题,提出了基于粒子阻尼系统控制方程的涡激载荷理论方程,研究了1/20风力机模型的振动控制,并进行了实验和数值分析。许多研究表明,配备调谐质量阻尼器 (TMD) 的风力涡轮机塔架可导致 RMS 响应降低率为 20% 至 40%。与TMD相比,粒子调谐质量阻尼器(PTMD)在单一地震荷载下具有更好的振动控制效果,并且在多灾害作用下仍然具有良好的振动控制能力,最大RMS(均方根)衰减率为35.55%。此外,提出了MPTMD(多粒子调谐质量阻尼器)来控制高阶振动模式,实现了65.93%的最大RMS降低率。结合谱图结果,证实了MPTMD控制高阶模态振动的能力。
