Abstract

The invention relates to the technical field of dampers, in particular to an eddy current damper and an eddy current tuned mass damper. The eddy current damper comprises a plurality of permanent magnets mounted on magnet mounting plates and a conductor plate mounted on a second end plate, the conductor plate is positioned between the magnet mounting plates, wherein the magnets at two sides of theconductor plate have opposite polarities, the magnet mounting plates are mounted on two side supporting plates, the side supporting plates are mounted on a same side of a first end plate, a rib plateis arranged between the side supporting plates, linear bearings are arranged on the rib plate and the first end plate respectively, a guide rod is arranged on the second end plate, and the guide rod penetrates through the rib plate and the linear bearings to connect the first end plate and the second end plate into a whole. The tuned mass damper comprises one or more of the eddy current dampers. In order to overcome the defects in the prior art, the problems that an existing damper is large in magnetic flux leakage and inconvenient for adjusting the damping coefficient are solved, and production and assembly are convenient.

Description

technical field [0001] The patent of the present invention relates to the technical field of dampers, in particular to an eddy current damper and an eddy current tuned mass damper. Background technique [0002] With the development of science and technology and urban construction, there are more and more high-rise buildings and long-span bridges. Although the strength and stiffness of such buildings are relatively easy to meet the design requirements, their own vibration frequency is often relatively low. For example, the natural vibration frequency of pedestrian bridges is generally around 2Hz, and the excitation frequency generated by people walking is also around 2Hz, which can easily cause bridge resonance, causing serious discomfort and panic to pedestrians, and also to the structure itself. damage, and even more seriously lead to pedestrian safety accidents. In addition, by changing the structure and improving its own natural frequency, the cost will often be greatly ...
