Multidimensional corrugated plate-tuned mass damping damping device and damping method

Abstract

The invention discloses a multi-dimensional corrugated plate-tuned mass damping shock-absorption device and a shock-absorption method thereof. The multi-dimensional corrugated plate-tuned mass dampingshock-absorption device comprises a bearing frame and a mass block arranged inside the bearing frame; the upper end of the mass block is hoisted in the bearing frame through a suspension-type stretching-resisting part, and the suspension-type stretching-resisting part comprises a plurality of first viscoelastic cylinder-type damping units and a plurality of first viscoelastic corrugated plates, wherein the upper end of each first viscoelastic cylinder-type damping unit is connected with the top of the bearing frame through a connecting swing rope, limiting piston rods inside the first viscoelastic cylinder-type damping unit extend out and are connected with the mass block through a connecting end plate; and the left side, the right side and the bottom of the mass block are connected withthe inner wall of the bearing frame in an abutting mode through rolling-type shock-absorption pressure-bearing mechanisms. The multi-dimensional corrugated plate-tuned mass damping shock-absorption device has the high assembling ability, the wide damping and rigidity adjustment domain, and the stable control capability to multi-directional vibration response of the structure under the complex excitation effect.

Description

technical field [0001] The invention relates to a multi-dimensional corrugated plate-tuning mass damping shock absorbing device and a shock absorbing method thereof. Background technique [0002] As a passive control device, the tuned mass damper has received great attention in the field of vibration control of high-rise building structures because of its simple structure, easy maintenance, and no need for external force assistance. Its main working principle is: [0003] By adjusting the dynamic parameters such as the mass, damping and frequency of the device itself, and using the principle of resonance to control the target mode shape of the control structure, in order to achieve the purpose of reducing the vibration response of the main structure, this requires the installed tuned mass damper device It has a large adjustable range of stiffness and damping, so as to adjust the excitation response of different dynamic states of the structure under the action of unknown vibr...

AI Technical Summary

Problems solved by technology

[0004] At present, the conventional tuned mass damper basically does not consider the damping energy consumption of the device itself during the working process, and the overall device is a low damping system, which basically does not have damping adjustability;

[0005] In addition, the stiffness contribution source in this type of device is single, and the adjustability is poor, which further limits the application and development of tuned mass dampers.
