Description
Technical field
The present invention relates to vibration control field, and in particular to a kind of current vortex liquid condenser.
Background technology
In today's society, all kinds of dampers are because have, easy construction small to original building structural modification, vibration damping control effect to show
The advantages of work and have application, such as Taipei 101 mansion, Shanghai center by extensive concern, and in building structure at home and abroad.
Traditional damper provides damping using hydraulic pressure fluid linking damper, while damping is provided, also has certain rigidity, it is impossible to do
To rigidity and being kept completely separate for damping, influence design analysis.Moreover, hydraulic pressure fluid linking damper also exist oil leak, be difficult maintenance, after
The problems such as phase is difficult to regulation, increase the difficulty and cost safeguarded.
Eddy-current damping is innovated greatly to the one of hydraulic pressure viscous damping.The principle of eddy current damper is, conductor mass
The cutting magnetic induction line in motion, according to faraday electromagnetic induction principle, will produce induced electromotive force in conductor, form electric whirlpool
Stream, converts vibrational energy into the heat of conductor, so as to realize vibration control.The advantage of eddy current damper is:Magnet with
Do not contacted directly between conductor, no frictional damping and abrasion;Not by ambient influnences such as temperature;In the absence of situations such as oil leaks, easily
In maintenance and good endurance.
But, existing eddy current damper is commonly used in the damping of vertical motion, for the damping of horizontal vibration
It is not good, and how further to strengthen the damping of eddy current damper, it is also that current field personnel focus on asking for consideration
Topic.
The content 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 result
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

There is damping screen and place damping fluid, when structure level to be damped vibrates, the power consumption unit cutting permanent magnet magnetic induction line heating
Power consumption, friction energy-dissipating of the damping fluid by rocking and with damping screen.
The damper of the present invention has double damping:First, structure occurred level to be damped drives iron to during vibration
Box does Horizontal Vibration, and cutting magnetic induction line motion occurs for the permanent magnet and power consumption unit for being adsorbed in can bottom, passes through power consumption
The heating power consumption of unit;Second, structure occurred level to be damped drives can to do Horizontal Vibration to during vibration, passes through damping
Liquid rock and between damping screen friction consumption vibrational energy., can be with significantly more efficient consumption by way of above two power consumption
Can, strengthen damping.
