Dynamic vibration absorption and energy consumption apparatus for reducing wind vibration response of high tower structure

Abstract

The invention discloses a dynamic shock-absorbing and dissipating energy device of reducing high tower structure wind vibration response, which comprises the following parts: steel pendulum tie1 whose one end hangs on the structure6, another end hangs with mass block2; the block2 can be used for boring iron shot or casting aluminum steel ball; the pendulum tie1 crosses the hole; the antifatigue damage device is installed in suspension construction; the pendulum tie1 crosses cylindrical compression spring31, whose both extremities of perforated bearing plate32 are clamped by fastener33; the upper, lower end of pendulum tie on mass block2 install antifatigue damage device3; the periphery of mass block is fixed with bump amortization dissipating energy component rubber ring4 whose amortization is more than 5%; There is a protection and repair suspender5 between structure6 and mass block. The control structure is effective, simple and reliable, which is installed in the mast cartridge for vibration damping control the mast structure shacking; the invention improves the control effect, which avoids the big and complicated device.

Description

technical field [0001] The invention relates to the fields of structural engineering and structural vibration control, in particular to a dynamic vibration absorption and energy consumption device for reducing the wind vibration response of a high tower structure. Background technique [0002] Structural vibration control is a new way of anti-seismic and wind-resistant structures that has emerged in the past ten years. After years of unremitting efforts, structural vibration control has made great progress in both theoretical research and engineering application. It is a milestone that, on the basis of a large amount of theoretical work, the National Natural Science Foundation of China established a key project (approval number: 59238160) in 1992 "Research on Seismic and Wind-resistant Control of Building Structures". Tower and Nanjing TV Tower) on the first bridge (Jiangyin Yangtze River Bridge) to carry out the application research of structural control system, which marks...

AI Technical Summary

Problems solved by technology

There have been many research results on TMD or AMD, but they are all limited to optimization and algorithm research. The application technology research of the control device and the quantitative analysis of the corresponding control results are still insufficient. The effectiveness, safety and security of the control device are still insufficient. Reliability monitoring studies are less reported
