Abstract

The invention relates to a tuned mass damper adjustable in three directions. The tuned mass damper is used for the vibration reduction of building construction and bridge engineering structures. The tuned mass damper comprises a bracket (2). Slings (1) are arranged on the upper part of the bracket (2). A mass block (5) is arranged on the lower parts of the slings. Springs (7) are arranged on the lower part of the mass block (5), and are positioned on a bottom plate (8). Viscous dampers (6) are arranged between the mass block (5) and the bottom plate (8). A guide rod (4) is connected to the bottom plate (8). The guide rod (4) and a guide sleeve (3) on the bracket form a guide mechanism to limit horizontal movement between the bracket and the bottom plate. The tuned mass damper can be used for the tuned reduction of the vibration of building construction structures, bridge engineering structures and the like in the three directions, natural vibration frequencies in the three directions can be conveniently adjusted, and the damping ratio of the three directions can also be adjusted according to needs.

Description

technical field [0001] The invention belongs to the technical field of vibration reduction of civil engineering structures, and relates to an adjustable three-way vibration-damping structure, in particular to a three-way tuned mass damper (TMD for short). Background technique [0002] The traditional anti-seismic or vibration-reducing methods for buildings and bridges are to resist by enlarging the section of the structure and adding more reinforcements. The result is that the larger the section, the greater the stiffness and the greater the vibration effect. The cost has been greatly increased, and the introduction of vibration control technology has solved this problem. The vibration control methods of engineering structures are mainly divided into: passive control, active control, semi-active control and hybrid control. The passive control technology is mainly the research on passive energy dissipation devices, and the three-way tuned mass damper TMD is one of the applica...
