Abstract

The invention belongs to the field of tuned massed dampers, and specifically is a tuned massed damper device. The tuned massed damper device comprises a mounting frame, a damping system, a horizontal sliding system and a vertical swinging system, wherein the damping system and the horizontal sliding system are arranged in the mounting frame, and the vertical swinging system is suspended below the horizontal sliding system; the horizontal sliding system comprises a first mass block, and the first mass block is mounted on the mounting frame in a mode that the mass block can move in the length direction of the mounting frame; the damping system comprises two dampers, the two dampers are arranged at the two sides, in the length direction of the mounting frame, of the first mass block symmetrically and correspondingly, one end of each damper is connected to the first mass block, and the other end of each mass block is connected to the corresponding edge, in the width direction, of the mounting frame; and the vertical swinging system comprises a second mass block, and the second mass block is mounted below the first mass block in an extensible swinging mode. According to the tuned massed damper device, the purposes that torsional vibration and flexural vibration of a power transmission tower are controlled simultaneously and wind-vibration of the power transmission tower in every direction is reduced can be achieved simultaneously.

Description

technical field [0001] The invention belongs to the field of tuned mass dampers, in particular to a tuned mass damper device. Background technique [0002] Due to its simple structure, low cost and reliable performance, the tuned mass damper is the most widely used structural control device in engineering. The vibration reduction control principle of the tuned mass damper device is: connect the TMD to the main structure, and transfer the energy of the main structure to the TMD by controlling the mode resonance of the inertial mass and the main structure, so as to achieve the purpose of suppressing the vibration of the main structure. [0003] Wind vibration can cause great damage to transmission towers, so how to reduce the impact of wind vibration on transmission towers has always been a difficult problem. Most of the traditional tuned mass dampers used to control the vibration of transmission towers are only designed to control the lateral or longitudinal bending of trans...
