Flat-turning compound type building vibration control system

Abstract

The invention relates to the field of restraining of vibration in systems, in particular to a flat-turning compound type building vibration control system. The flat-turning compound type building vibration control system comprises a horizontally moving control unit and a rotating control unit; the horizontally moving controlling unit is installed in a controlled structure, and the rotating controlunit is installed above the horizontally moving control unit; the horizontally moving control unit mainly comprises a fixed base, a first rail plate, a first moving plate, a second rail plate, and asecond moving plate; and the rotating control unit comprises a power conveying base, a driving machine, a speed reducer, an output shaft, a rotating inertia disc and a flange disc. According to the flat-turning compound type building vibration control system, a horizontally moving vibration form can be controlled, and a shimmy vibration form can also be controlled and reversed, so that the purposeof vibration control is achieved, and the problems that a horizontal moving TMD loses efficacy to gyratory shimmy motion; the horizontally moving AMD control efficiency is low, and the effect is bad;and a negative tune rotating inertia damper is low in controlling application robustness, complex in frequency modulation technology, and small in application range are solved.

Description

technical field [0001] The invention relates to the field of vibration suppression in a system, in particular to a horizontal-rotation composite building vibration control system. Background technique [0002] In recent years, with the development of the economy and the progress of society, people's requirements for living space have also been continuously improved, and the country's investment in infrastructure has continued to increase. Highways, railways, bridges, high-rise buildings, and long-span space structures are constantly being built. In addition, people are also exploring and developing a wider space, exploring "deep sea" and "deep space", and structures such as ocean platforms and space stations are also developing rapidly. These space structures are inevitably subjected to various loads, including static loads and dynamic loads, during construction and later operation. During the use of the structure, it is often the dynamic load that has a greater impact on ...

Problems solved by technology

[0009] The main purpose of the present invention is to provide a translational compound building vibration control system to solve the failure of the translational TMD to control the rotary shimmy motion in the prior art; the translational AMD control efficiency is low and the effect is poor; the passive tuning moment of inertia Damper control is applicable to the problems of low robustness, complex frequency modulation technology, and small application range. The present invention provides a suitable force acting on the controlled structure through the actual motion of the structure, the AMD motion of the control device, and the rotation of the moment of inertia. , can control both the form of translational vibration and the form of torsional shimmy vibration to achieve the purpose of vibration control
