Fan tower tube vibration control eddy current tuning mass damper
The invention provides a fan tower tube vibration control eddy current tuning mass damper. The mass damper is arranged inside a fan tower tube (1) and comprises a sleeve (2), a base plate (7) arrangedat the bottom of the sleeve (2) and a copper plate (6) and a permanent magnet (4) which are arranged inside the sleeve (2). The permanent magnet (4) is suspended at the top of the sleeve (2). The copper plate (6) is fixed to the base plate (7) and can perform vibration reduction on a fan tower tube, and the damping effect is good. The magnitude of magnetic damping can be flexibly adjusted, and the large adjusting range is obtained. The damper is arranged inside the fan tower tube (1), a connecting plate (8) is fixed to the inner wall of the fan tower tube (1) in a welded mode, and the weatherresistance is good. The rigidity of the damper is changed by changing the diameter and length of a suspender (3), the rigidity of the damper is adjustable flexibly, no mechanical friction problem orsealing problem exists, and the reliability and durability are good.
本发明提供一种风机塔筒振动控制电涡流调谐质量阻尼器，质量阻尼器置于风机塔筒(1)内部，其包括套筒(2)、置于套筒(2)底部的底板(7)以及置于套筒(2)内部的铜板(6)和永磁体(4)，永磁体(4)悬挂于套筒(2)顶部，铜板(6)固定于底板(7)上，能够对风机塔筒进行减振，且减振效果好；能够灵活调节磁阻尼的大小，具有较大的调节范围；本发明置于风机塔筒(1)内部，连接板(8)通过焊接方式固定在风机塔筒(1)内壁，耐候性好；本发明通过改变吊杆(3)的直径和长度改变阻尼器的刚度，使得阻尼器刚度零活可调，且不存在机械摩擦问题和密封问题，可靠性和耐久性好，且本发明提供的阻尼器刚度零活可调，且不存在机械摩擦问题和密封问题，可靠性和耐久性好。
