Two-way horizontal adjustable tuned mass damper

Abstract

The invention relates to a two-way horizontal adjustable tuned mass damper which comprises a rectangular base that is provided with a longitudinal trolley, wherein a transverse trolley is arranged on the top of the longitudinal trolley; the front end and the rear end of the longitudinal trolley are respectively provided with a first damper; one end of each first damper is connected with a longitudinal trolley body by a universal coupling, and the other end of the first damper is connected with the base by another universal coupling; the front end and the rear end of the transverse trolley are respectively provided with a second damper; one end of each damper is connected with a transverse trolley body by a universal coupling, and the other end of the second damper is connected with a second sliding block by another universal coupling; two longitudinal sliding rails are respectively arranged at the two sides of the base; the second sliding blocks are respectively matched with the longitudinal sliding rails; and a balancing weight is arranged on the transverse trolley. The two-way horizontal adjustable tuned mass damper is capable of realizing two-way shock absorption, and only needs one set of balancing weight, so that the weight of the tuned mass damper is lighter than that of the traditional tuned mass damper, the burden of a building is low, and the damping effect is good; and the two-way horizontal adjustable tuned mass damper is especially suitable for buildings such as a high-voltage power transmission tower and a radio tower.

Description

technical field [0001] The invention relates to a two-way horizontally adjustable tuned mass damper. Background technique [0002] With the development of economy and society, the development trend of materials in high-rise buildings is lightweight and high-strength materials, but the large number of applications of these materials leads to the relative reduction of stiffness and damping of high-rise buildings. When an earthquake occurs, the seismic response of the building (such as top displacement, bottom axial force, etc.) is too large, which affects the safe and stable operation of tall buildings, causes serious damage to the building, and even collapses, causing huge economic losses. The tuned mass damper is a classic shock-absorbing control device that generates vibrations during an earthquake and drives the tuned mass damper to vibrate together. The inertial force generated by the relative motion of the tuned mass damper reacts on the building to reduce the structura...

AI Technical Summary

Problems solved by technology

The current tuned mass dampers are all shock absorbers. Multi-directional shock absorption requires the installation of multiple tuned mass dampers, which increases the burden on the building, and the frequencies in each direction are different, so the shock absorption effect is not good.
