Eddy current magnetic resistance hyperboloid friction pendulum support

Abstract

The invention discloses an eddy current magnetic resistance hyperboloid friction pendulum support. The eddy current magnetic resistance hyperboloid friction pendulum support is composed of an upper support plate, an upper magnetic conductive plate, an upper eddy current plate, an upper wear-resisting plate, a permanent magnet spherical crown, a lower wear-resisting plate, a lower eddy current plate, a lower magnetic conductive plate and a lower support plate, wherein the permanent magnet spherical crown is composed of an upper friction plate, a permanent magnet, a support unit and a lower friction plate. When the eddy current magnetic resistance hyperboloid friction pendulum support is under the action of horizontal earthquake, the permanent magnet spherical crown moves reciprocatingly between the upper curved wear-resisting plate and the lower curved wear-resisting plate, and according to the principles of electromagnetism, the upper eddy current composite plate and the lower eddy current composite plate reciprocatingly cut off magnetic induction liens to produce eddy current and accordingly to generate magnetic damping, and further the magnetic damping consumes the motion energyof the eddy current magnetic resistance hyperboloid friction pendulum support together with coulomb friction damping produced by the friction plates. The eddy current magnetic resistance hyperboloid friction pendulum support has the advantages of being maintenance-free, low in manufacturing price, good in weather resistance and the like and belongs to the technical field of friction pendulum supports.

Description

technical field [0001] The invention relates to the technical field of friction pendulum supports, in particular to eddy current magnetic damping compound hyperboloid friction pendulum supports. Background technique [0002] With the large-scale construction of infrastructure and the substantial improvement of the industrial level, more attention has been paid to the isolation and vibration control of basic engineering such as bridges and large public buildings. Under the action of vibration, damage to basic engineering and industrial equipment will bring great losses to people's lives and property. The traditional hyperboloid friction pendulum support uses the Coulomb friction damping between the friction plate and the spherical cap (slider) to dissipate the vibration energy, and can provide a higher vertical bearing capacity, but the existing hyperboloid friction pendulum Bearing technology is accompanied by the following problems: [0003] 1. The damping force of the fr...

AI Technical Summary

Problems solved by technology

[0003] 1. The damping force of the friction pendulum support cannot be changed according to the horizontal sliding speed and restoring force of the support, and it cannot provide different damping forces for the upper structure under different horizontal movement speeds;

[0004] 2. Friction damping is greatly affected by the friction coefficient of the friction pair and the vertical load of the support

However, adding a certain number of dampers in the structural isolation layer will also bring many problems, such as: increased engineering cost, more complicated design and installation, etc.
