Description
Technical field
The present invention relates to a kind of current vortex friction pendulum vibration absorption and isolation support, belongs 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 technology
In recent years, earthquake (such as Tangshan Earthquake, Wenchuan earthquake, Yaan earthquake), typhoon (sea anemone, Mai Sha, Sang Mei etc.) etc.
The frequent generation of extreme load causes the loss for being difficult to bear to the life of people with property, and China is located at Pacific Rim earthquake
Band-Eurasian earthquake zone, earthquake take place frequently, and Southeastern Coastal Cities often undergo typhoon puzzlement.To reduce macroseism, high wind soil under action wood
Economy, loss caused by the damage of engineering structure, research and develop new seismic isolation device, enhancing building, the shock resistance of bridge structure
Can, it is to ensure 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 sufficiently 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 actual work
Played an important role in journey structure, such as lead rubber laminated bearing, high-damp rubber support, friction-pendulum shock-insulation support.So
And traditional vibration absorption and isolation support mainly subtracts the purpose of shock insulation as leading indicator to reduce horizontal rigidity to realize, the damping of bearing
Energy dissipation capacity is relatively weak, and under the effect of the extreme load such as macroseism, high wind, it is normal using traditional isolation measure and seismic isolation device
It can not meet to subtract shock insulation requirement.Domestic and foreign scholars have done many research on seismic isolation device, and propose various new subtracts shock insulation
Device, as existing New Isolation Bearing has, steel-lead combination core subtracts shock insulation rubber bearing, soft steel core rubber mat spring assembly subtracts
Shock isolating pedestal, multidimensional subtract separation lead-core rubber, variable curvature friction-pendulum shock-insulation support, height-adjustable friction-pendulum shock-insulation support,
A kind of two-way variable curvature friction-pendulum shock-insulation support etc..But above novel base for supporting is to give full play to support material itself energy-dissipating property
Based on, the damping of its own is smaller, is still required for being lifted the damping energy dissipation performance of vibration absorption and isolation support.To realize heavy damping power consumption
Performance objective, often damper (hydraulic damper, viscoelastic damper etc.) is used in large scale structure, also makes the energy dissipation capacity of structure
Greatly reinforce, problem it is critical that the energy-dissipating property of such damper can move back with the degeneration of damper material property itself
Change, durability is poor.The aseismic fortification objects of " no collapsing with strong earthquake " are realized, avoid structure from being fallen under macroseism, high wind effect
Collapse destruction, subtract seismic isolation technology means using new, strengthen the damping energy dissipation performance of vibration absorption and isolation support, be give full play to bearing 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 produces damping force to lift damping
The new technology of performance.Its principle is：Motion conduct in local magnetic field because of cutting magnetic induction line and caused by current vortex (conductor circumference
Ring induced electromotive force, induced-current caused by direction), so as to which obstruction magnetic is being produced caused by permanent magnet between magnetic field and conductor
Iron and the damping force of conductor relative motion, due to the electricresistance effect of conductor, the kinetic energy of conductor is converted by conductor current vortex
Dissipated for heat energy, reach 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, in the absence of leakage, close
The problems such as envelope, Properties of Friction Materials are degenerated, have reliability height, good endurance, damping energy dissipation performance it is strong, it is antifatigue, construct phase
The advantages that to simple, easy care.
For the seismic response under more effectively control structure severe earthquake action, it is necessary to using current vortex energy-dissipating and shock-absorbing technology
Research and develop new seismic isolation device.Currently, the research and development such as " variable curvature friction-pendulum shock-insulation branch on 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, and construction is more complicated, inconvenience
Safeguard.
It would therefore be highly desirable to solve the above problems.
