Electromagnetic damping composite sliding plate support

Abstract

The invention discloses an electromagnetic damping composite sliding plate support which is composed of an upper connecting plate, an elastic support part, a permanent magnetic type sliding body, an eddy current sliding compound plate and a lower connecting plate. The elastic support part is composed of an upper sealing plate, a lower sealing plate, an elastic body and a stiffening plate, wherein the elastic body and the stiffening plate are arranged between the upper sealing plate and the lower sealing plate in an alternate overlapped mode. The permanent magnetic type sliding body is formed by overlapping a permanent magnet and a sliding material and is fixed to the lower portion of the elastic support part in an embedded mode. The eddy current sliding compound plate is formed by sequentially overlapping a sliding panel, an eddy current plate and a magnetic conduction plate. The permanent magnetic type sliding body and the eddy current sliding compound plate form a friction pair. When the electromagnetic damping composite sliding plate support is subjected to horizontal power loads, the upper portion and the lower portion of the support slide relatively, and electromagnetic damping is generated through reciprocating motion. Compared with the prior art, the electromagnetic damping composite sliding plate support can provide controllable damping dissipation energy and has the advantages of being high in vertical loading force, free of maintenance, low in manufacturing cost, superior in weather resistance and the like.

Problems solved by technology

Ordinary elastic skateboard isolation bearings can provide high vertical bearing capacity, low horizontal stiffness and strong horizontal deformation capacity, but the existing elastic skateboard bearing technology is accompanied by the following problems that have not been resolved

[0003] 1) The elastic slide bearing cannot provide effective damping for the seismic isolation structure under the condition of low horizontal stiffness;

[0004] 2) The skateboard support cannot adjust the damping parameters according to the input of earthquake vibrations of different intensities

Compared with the existing technology, the above two patents have the advantages of high vertical bearing capacity and long-term performance stability. However, this type of slide bearing cannot provide adjustable damping. Angle limits, usually this type of bearing needs to be used together with a damper or a lead rubber bearing
