Intelligent electromagnetic control vibration isolation support

Abstract

The invention provides an intelligent electromagnetic control vibration isolating support. The intelligent electromagnetic control vibration isolating support comprises a traditional vibration isolating support, a pressure induction device, an electromagnet upper plate, an electromagnet lower plate, an upper transmission connecting rod, a lower connecting plate, a one-way bearing, a transmission gear, a direct-current generator, a control circuit, a working circuit and a storage battery. Mechanical energy generated when a structure slides horizontally is transmitted to an energy system through a mechanical transmission system under regulation and control of a control system, and is converted into electric energy by the direct-current generator, multistage earthquake control is implemented through the control circuit comprising a pressure sensor, namely, only a storage battery charging circuit is started when a small or middle earthquake occurs, and an electromagnet system working circuit is started when a major earthquake occurs. Moreover, counterforce for driving the direct-current generator also controls horizontal movement of the vibration isolating support. The intelligent electromagnetic control vibration isolating support is suitable for a vibration isolating structure of which a support possibly has over-large tensile stress, and can be used with various vibration isolating supports. Besides, the intelligent electromagnetic control vibration isolating support is novel in design concept, and has good three-dimensional mechanical property; and integration degrees of a mechanical system, an electromagnetic system and the control system are high.

Description

technical field [0001] The invention relates to an intelligent electromagnetic control shock-isolation support, which belongs to the technical field of shock-absorption and shock-isolation of engineering structures. Background technique [0002] Due to its suddenness, randomness, and destructiveness, earthquake disasters bring harm to the natural environment and human society. With the development of economy and society and the advancement of science and technology, engineers began to gradually pursue the easy repair of structures and the recoverability of social functions on top of the basic requirements of ensuring the safety of life and property in disaster-stricken areas. Scientific research and engineering applications have confirmed that the seismic isolation structure system is a structural control technology with a significant shock absorption effect, but it is still mostly used in structural systems with low superstructure heights. The application of seismic isolat...

AI Technical Summary

Problems solved by technology

The application of seismic isolation technology to high-rise buildings faces two main challenges: (1) the isolation bearing will produce excessive horizontal displacement (deformation) under a large earthquake; (2) due to the large overturning moment of the superstructure or vertical earthquake, Isolation bearings located at the edge of the structure have the potential to exceed the tensile stress or the risk of bearing detachment

Both of the above may cause the failure of the seismic isolation bearing, resulting in unpredictable and catastrophic consequences
