A tuning mass damping device

Abstract

The invention provides a tuned mass damping device. The tuned mass damping device comprises a base, a mass block, an elastic component and a damper, wherein the elastic component and the damper are both installed between the base and the mass block, the two ends of the elastic component and the damper are connected with the base and the mass block correspondingly, and the mass of the mass block can be adjusted. The natural frequency of the tuned mass damping device can be changed by adjusting the mass of the mass block so as to enable the natural frequency to be close to or even equal to the natural vibration frequency of a building structure, and thus the best damping effect of the tuned mass damping device is achieved. Particularly, when the tuned mass damping device is installed on the building structure, the natural frequency of the tuned mass damping device can be adjusted but the natural frequency of the tuned mass damping device does not need to be dismounted and mounted, the installing and debugging steps of the natural frequency of the tuned mass damping device are simplified, and the construction difficulty and construction time are reduced.

Description

technical field [0001] The invention relates to a vibration damping device, in particular to a tuned mass damping device. Background technique [0002] With the development of urban construction, various high-rise, super high-rise buildings, thin-high structures, and long-span buildings are increasing day by day. At the same time, the urban traffic network is becoming more and more developed, and bridge structures such as various long-span pedestrian bridges have been widely used, which has brought great convenience to people's travel. However, although the strength and stiffness of such thin and tall buildings and bridges are relatively easy to meet the design requirements, the frequency of their vertical vibration is generally relatively low. It will cause uncomfortable feeling, and at the same time, it will cause structural damage to the structure itself, and even seriously threaten the safety of people and vehicles. [0003] How to prevent such large-span, low-frequenc...

AI Technical Summary

Problems solved by technology

However, in practical applications, due to errors in the estimation of the natural frequency and the production or installation of the tuned mass damper, the error between the natural frequency of the existing tuned mass damper and the natural frequency of the structure is relatively large, and the tuning Mass dampers are not working to their maximum effect
