Description
Technical field
The present invention relates to vibration control fields, and in particular to a kind of current vortex liquid condenser.
Background technique
In today's society, small to original building structural modification, easy for construction, vibration damping control effect is aobvious because having for all kinds of dampers
The advantages that work and have application by extensive concern, and in building structure at home and abroad, such as Taipei 101 mansion, Shanghai center.
Traditional damper provides damping using hydraulic fluid linking damper and also has certain rigidity while providing damping, can not do
It is kept completely separate to rigidity with what is damped, influences design analysis.Moreover, hydraulic fluid linking damper there is also oil leak, be not easy to conserve, after
Phase is difficult to the problems such as adjusting, and increases the difficulty and cost of maintenance.
Eddy-current damping is innovated greatly to the one of hydraulic viscous damping.The principle of eddy current damper is conductor mass block
Cutting magnetic induction line during exercise will generate induced electromotive force according to faraday electromagnetic induction principle in conductor, form electric whirlpool
Stream, converts vibrational energy into the heat of conductor, to realize vibration control.The advantage of eddy current damper is: magnet with
It is not contacted directly between conductor, no frictional damping and abrasion；It is not influenced by environment such as temperature；There is no the situations such as oil leak, easily
In maintenance and durability it is good.
But existing eddy current damper, it is commonly used in the damping of vertical motion, for the damping of horizontal vibration
It is bad, and the damping of eddy current damper how is further strengthened, and field personnel focus on asking for consideration at present
Topic.
Summary of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of good damping results
Current vortex liquid condenser.
The purpose of the present invention can be achieved through the following technical solutions: a kind of current vortex liquid condenser, the damper
It is arranged between the bottom plate and top plate of structure to be damped, the damper includes the can for being fixedly connected on top plate bottom, absorption
Permanent magnet in can bottom and the energy consumption unit that is fixed at the top of bottom plate and is located at immediately below permanent magnet are set in the can
There is damping screen and places damping fluid, when structure level to be damped vibration, the energy consumption unit cutting permanent magnet magnetic induction line fever
Energy consumption, the damping fluid pass through shaking and the friction energy-dissipating with damping screen.
Damper of the invention is with double damping: first, when Horizontal Vibration occurs for structure to be damped, drive iron
Box does Horizontal Vibration, and cutting magnetic induction line movement occurs for the permanent magnet and energy consumption unit for being adsorbed in can bottom, passes through energy consumption
The fever of unit is consumed energy；Second, when Horizontal Vibration occurs for structure to be damped, drives can to do Horizontal Vibration, pass through damping
The shaking of liquid and the friction between damping screen consume vibrational energy.By above two energy consumption mode, significantly more efficient can consume
Can, enhance damping.
The top plate bottom fastening bracket, the can are connect by swing rope with bracket.
Support is equipped at the top of the bottom plate, the energy consumption unit is fixed on the support.
The energy consumption unit includes the conductor plate being located at below permanent magnet and the magnetic conductive board being arranged in below conductor plate, institute
It is fixed on the support to state magnetic conductive board.Magnetic conductive board is set in the lower section of conductor plate, can be effectively enhancing magnetic field strength, increase energy consumption
The fever of unit is consumed energy.
The material of the conductor plate is copper or aluminium, and the material of the magnetic conductive board is one of iron, cadmium or cobalt.
The distance between the conductor plate and permanent magnet are 5~10mm.When within this range, magnetic induction intensity is stronger, leads
The fever energy-dissipating property of body plate is preferable, is capable of the vibration of effective control structure.
The material of the permanent magnet is one of rare earth permanent-magnetic material, SmCo, ni-Cd cobalt or ferrite permanent-magnet materials.
The material of the damping screen is that copper or iron, damping screen parallelly distribute in can, and the quantity of damping screen are 1
~5.
The damping fluid includes water or silicone oil.
Compared with prior art, the beneficial effects of the present invention are embodied in: traditional viscous damping is replaced with eddy-current damping,
It can be improved the stability and durability of damper, simplify the design of damper.And dexterously compound upper liquid condenser is reinforced
The effectiveness in vibration suppression and energy dissipation capacity of damper.Advantageously ensure that safety and the durability of structure.
