Eddy-current energy-dissipating vibration-absorbing device for controlling horizontal and torsional directions

Abstract

The invention discloses an eddy current energy dissipation vibration damping device capable of controlling vibration in the horizontal direction and the torsion direction. The eddy current energy dissipation vibration damping device comprises a box, a tuned mass damper (TMD) is connected with the top face of the box, the TMD comprises a vertical cantilever round pipe, two round rods are horizontally inserted in the lower end of the cantilever round pipe in a penetrating mode, and the bottom end of the cantilever round pipe is connected with a mass block; the two round rods are perpendicularlycrossed, the two ends of each round rod are connected with mass blocks correspondingly, conductor plates are connected to the bottom ends of the five mass blocks correspondingly, and five permanent magnets corresponding to the lower faces of the five mass blocks are connected to the bottom face of the box; and a horizontal damping net and a vertical damping net are mounted in each mass block, eachhorizontal damping net is fixed to the inner wall of the corresponding mass block, one end of each vertical damping net is fixed at the bottom of the corresponding mass block, the other end of each vertical damping net and the corresponding horizontal damping net are fixed, and the interior of each mass block is filled with liquid.

Description

technical field [0001] The invention belongs to the field of vibration reduction control of towering structures, in particular to an eddy current energy consumption vibration reduction device for controlling horizontal and torsional directions, which can be used for vibration reduction control in civil engineering structures. Background technique [0002] In today's era, towering structures such as transmission towers and communication towers are developing rapidly, and their vibration problems have been widely concerned and studied. The main loads borne by the towering structure include the structure's own weight, equipment weight, wind load and earthquake action, and because of its high height, relatively small cross-section, and low structural rigidity, it is easy to generate large-scale vibrations, resulting in structural failures. Fatigue damage or destruction increases the vulnerability of structures. Therefore, the vibration control of towering structures under wind l...
