Abstract

The invention discloses a vibration reduction control device of a tuned mass damper. The vibration reduction control device of the tuned mass damper comprises a supporting bracket, a mass block and a damping element, wherein extension springs are mounted between the periphery of the mass block and the supporting bracket in a uniform distribution manner; the extension springs are arranged horizontally; one end of every extension spring is connected with the supporting bracket, and the other end of the corresponding extension spring is connected with the mass block; the damping element is arranged between the bottom of the mass block and a bottom plate of the supporting bracket; the mass block comprises multiple steel plates, and is in a cubic or cylindrical integral structural shape, when the mass block is cubic, the extension springs are uniformly distributed on the four side surfaces of the mass block, and when the mass block is cylindrical, the extension springs are uniformly distributed on the circumferential side surface of the mass block in an equal-angle manner. The control device is scientific in design, convenient to operate and use, low in cost, good in economical efficiency and extremely high in vibration reduction sensitivity, can be used for controlling horizontally universal (randomly directional) vibration, and is applicable to a low-frequency state, a medium-frequency state and a high-frequency state at the same time; further, a frequency range can be regulated through adjusting the rigidity of the extension springs or the weight of the mass block or adjusting the pendulum length of a pendulum rope.

Description

technical field [0001] The invention relates to a wind resistance and vibration reduction device for towering and soft structures such as building structures, bridges, power transmission towers, petroleum liquefaction reaction towers, and storage tanks in low-frequency conditions, and especially relates to a device that can control vibrations in any horizontal direction (any direction). Controlled tuned mass damper damping control device. Background technique [0002] Engineering structures will produce harmful vibrations under the action of earthquake, wind excitation, human and other factors, which will make people feel panic or uncomfortable, and seriously affect the durability of the structure; the application of tuned mass dampers can effectively control structural vibration and achieve better Good vibration damping effect, and has been proven in many practical engineering applications. [0003] A tuned mass damper (Tuned Mass Damper, referred to as TMD) is mainly comp...
