Description

Technical Field

[0001] The utility model relates to the technical field of tuned mass dampers, in particular to a tuned mass damper which is easy to install and maintain. Background Art

[0002] The tuned mass damper is composed of a mass block, a spring and a damping system. The vibration frequency is adjusted to the vicinity of the main structure frequency, and the structural resonance characteristics are changed to achieve a shock-absorbing effect. The purpose of installing the tuned mass damper into the structure is to reduce the energy dissipation requirement of the basic structural member under the action of external forces; in this case, this reduction is achieved by transferring some of the energy of the structural vibration to the tuned mass damper composed of an auxiliary mass-spring-damper cylinder system fixed or connected to the main structure in the simplest form. Patent: CN 210918422U discloses a tuned mass damper, including a mass block, an elastic element, an eddy current damper assembly, a guide assembly and a mounting assembly. The eddy current damper assembly includes a first permanent magnet and a second permanent magnet mounted in parallel on a magnet fixing plate, and a conductor plate arranged between the permanent magnets. The conductor plate moves between the permanent magnets to form an overlapping area different from the magnets to achieve the damping size adjustment of the eddy current damper assembly.

In addition, the limit structure on the traditional tuned mass damper does not have the ability of magnetic shock absorption. Therefore, we make improvements on this and propose a tuned mass damper that is easy to install and maintain. Utility Model Content
