An eddy current three-dimensional vibration isolation bearing

Abstract

The invention discloses an eddy current three-dimensional shock insulation support which comprises a base and an upper shock insulation support. The base comprises a first iron plate and an upper-layer copper plate. The first iron plate and the upper-layer copper plate are connected through a first screw rod, and the upper surface of the upper-layer copper plate is fixedly connected with a hard slab. The four corners of the lower surface of the first iron plate are each fixedly connected with a horizontal adjuster, and the upper shock insulation support comprises a second iron plate, a hard plastic plate, four guide wheel balls and a rubidium magnet array. The four corners of the lower surface of the hard plastic plate are each fixedly connected with a guide wheel, and the second iron plate and the hard plastic plate are connected through a second screw. The lower surface of the second iron plate is fixedly connected with the rubidium magnet array, the four edges of the upper surface of the hard slab are fixedly connected with eight straight rods, and each straight rod is connected with the side face, at the corresponding position, of the hard plastic plate through a soft spring. The eddy current three-dimensional shock insulation support has good three-dimensional shock insulation capacity, and large damping can be achieved when the horizontal rigidity of the whole device is small.

Description

technical field [0001] The invention relates to an electric eddy current three-dimensional shock-isolation support. Background technique [0002] In today's society, big data technology has gradually penetrated into various fields. As the carrier of massive information storage and high-performance computing, the storage unit, computing unit and other equipment in the big data center play a pivotal role. Once damaged by an earthquake, it will cause major damage. In terms of economic loss and social impact, domestic and foreign research on the isolation of important equipment in big data centers is still relatively small; in addition, cultural relics are treasures for us to understand social processes and human development processes, and carry the spiritual wealth of human civilization. Earthquakes have records of damage to cultural relics. Since the 1990s, the United States and Japan have successively proposed anti-shock isolation technology for cultural relics. Horizontal ...

Problems solved by technology

[0004] Although the current seismic isolation theory is relatively mature and the effect of seismic isolation equipment is relatively good, there are still some deficiencies, which are mainly manifested in: (1) The current seismic isolation equipment is mainly for building structures or large-scale equipment, and its volume is relatively large. There are few miniaturized seismic isolation devices for important equipment or precious cultural relics; (2) traditional seismic isolation devices are mostly horizontal, and it is difficult to resist the destructive effect of vertical earthquakes; (3) existing seismic isolation devices mainly use external damping The form of the device improves its energy consumption and limit capacity, the structure is relatively complex, and the economy is poor; (4) Some materials such as rubber and viscous liquid used in some seismic isolation bearings still have aging or temperature effects
