The invention relates to the technical field of engineering structure vibration control, in particular to a tuned mass damper which comprises a mass block, a spring and at least one adjustable damping mechanism. The spring is fixedly arranged on the controlled part, and the other end is connected with the mass block; the at least one adjustable damping mechanism comprises two conductor plates which are arranged at an interval and are arranged on the mass block or the controlled part; at least one radial magnetic permanent magnet is arranged between the two conductor plates, and at least one end of the radial magnetic permanent magnet is connected with the mass block or the controlled part; the rotary adjusting structure is arranged at the end part of the radial magnetic permanent magnet and is used for adjusting the circumferential direction of the radial magnetic permanent magnet; when the conductor plate is arranged on the mass block, the radial magnetic permanent magnet is arranged on the controlled part, and when the radial magnetic permanent magnet is arranged on the mass block, the conductor plate is arranged on the controlled part. The problem that in the prior art, the damping size is adjusted by adjusting a gap between an eddy current plate and a permanent magnet, and damping parameters cannot be accurately adjusted can be solved.
Description
technical field [0001] The invention relates to the technical field of engineering structure vibration control, in particular to a tuned mass damper. Background technique [0002] With the continuous development of technology, the number of long-span bridges and high-rise buildings in the civil engineering industry is also increasing. With the increase of the span of the bridge and the increase of the height of the building, the dynamic response of the structure also increases when it is subjected to dynamic loads. Excessive vibration will lead to various structural damages and even cause structural failure. [0003] Tuned mass damper (TMD) has been applied in many bridges and high-rise buildings, and it has been proved to be an effective measure to reduce structural vibration. TMD is a mechanical device composed of mass blocks, springs and damping elements. It absorbs the vibration energy of the main structure into the mass and dissipates it. [0004] The key parameters...
