Description
Technical field
The present invention relates to a kind of current vortex friction pendulum vibration absorption and isolation supports, belong to the knot such as bridge, house of field of civil engineering
Structure subtracts shock insulation control technology more particularly to a kind of current vortex friction pendulum vibration absorption and isolation support.
Background technique
In recent years, earthquake (such as Tangshan Earthquake, Wenchuan earthquake, Yaan earthquake), typhoon (sea anemone, Mai Sha, Sang Mei etc.) etc.
The frequent of extreme load occurs to cause the loss for being difficult to bear to the life and property of people, and China is located at Pacific Rim earthquake
Band-Eurasian earthquake zone, earthquake take place frequently, and Southeastern Coastal Cities often undergo typhoon to perplex.To reduce macroseism, the lower building of high wind effect
Economy caused by the damage of engineering structure, loss research and develop novel seismic isolation device, enhancing building, the shock resistance of bridge structure
Can, it is to guarantee structure, people's life, the important technical of property safety.
As superelevation, super-span building, Longspan Bridge continue to bring out, Seismic Isolation And Dissipation of Civil Structures device obtained adequately grinding
Hair and application, and good damping and isolation effect is achieved, to ensure the safe and reliable of engineering structure, seismic isolation device is in practical work

Collapse destruction, subtract seismic isolation technology means using novel, enhance the damping energy dissipation performance of vibration absorption and isolation support, be give full play to support subtract every
The key of shock stability.
Current vortex energy-dissipating and shock-absorbing technology is that a kind of relative motion using magnetic field and conductor generates damping force to promote damping
The new technology of performance.Its principle are as follows: current vortex (the conductor circumference that the motion conduct in local magnetic field is generated by cutting magnetic induction line
The circumferential induced electromotive force of direction generation, induced current), magnetic is hindered to generate between the magnetic field that permanent magnet generates and conductor
The damping force of iron and conductor relative motion, due to the electricresistance effect of conductor, the kinetic energy of conductor is converted by conductor current vortex
It is dissipated for thermal energy, reaches energy-dissipating and shock-absorbing purpose.Compared to traditional Seismic Isolation And Dissipation of Civil Structures device (such as hydraulic damper, viscoplasticity
Damper, lead rubber laminated bearing etc.), current vortex energy-dissipating and shock-absorbing technology consumes energy not against mechanical friction, and there is no leakages, close
The problems such as envelope, Properties of Friction Materials are degenerated, with high reliablity, durability is good, damping energy dissipation performance is strong, antifatigue, construction phase
To the advantages that simple, easy to maintain.

Research and develop novel seismic isolation device.Currently, the research and development such as " variable curvature friction-pendulum shock-insulation branch about novel friction pendulum vibration absorption and isolation support
Seat ", " height-adjustable friction-pendulum shock-insulation support ", " friction-pendulum shock-insulation support with self-checking function ", a kind of " two-way variable curvature
Friction-pendulum shock-insulation support " etc., but mainly to make full use of based on damping device own material performance, the damping of material itself compared with
It is small, and energy-dissipating property can degenerate with the degeneration of damping device material property itself, durability is poor, constructs more complex, inconvenience
Maintenance.
It would therefore be highly desirable to solve the above problems.
