摘要：
Based on a basin tuned and particle damper suitable for vibration control in wind turbine tower, a series of experiments were carried out to study the influence of three design parameters including the structural frequency, the mass ratio and the particle number in each container on the damping effect. A shaker test platform was introduced to simulate the first-order vibration of the wind turbine tower under the emergency shutdown case. The displacement response of the shaker test platform was measured by the laser displacement sensor. The damping ratio of the shaker test platform was obtained by linear fitting the peak value of displacement time histories. The results show that the proposed damper with different design parameters can effectively increase the system damping ratio of the shaker test platform. The influence rules of the structural frequency, the damper mass ratio and the particle number per container on the damping effect was summarized. It is found that the damper has the advantage of being insensitive to the structural frequency, which is available for vibration control in wind turbine tower. The research can provide a reference for the optimal design and application of this type of damper. © 2021, Solar Energy Periodical Office Co., Ltd. All right reserved.
