Background technology
Traditional seismic design of structures is come " resisting " geological process by the performance of enhancing structure itself.But it is due to people
Can not still estimate structure the future earthquake intensity and characteristic that may meet with exactly, under severe earthquake action, structure is likely to not
The requirement of security is met, so as to occur heavy damage, or even is collapsed.The raising building that appears as of structural vibration control technology is tied
Security of the structure under severe earthquake action provides an effective way.Tuned mass damper (Tuned Mass Damper,
TMD) it is exactly a kind of common vibration absorber, its single order vibration frequency is made by the additional mass or rigidity that tune in building structure
It is consistent with the fundamental frequency of structure, so as to reach the purpose of vibration damping.Good TMD effectiveness in vibration suppression needs the larger additional matter of structure
Amount, however, the additional mass of increase structure is unfavorable to reducing the financial cost and increase building safety of building structure.
Therefore, there is favourable and unfavorable factor in tuned mass damper simultaneously in vibration damping control process to structure.How this is removed
Unfavorable factor, makes TMD not increase the unnecessary additional mass of structure, and structural vibration reduction control tool is of great significance.
The content of the invention
The purpose of the present invention is to carry out building structure vibration damping using TMD, and emphasis is that solution never increases unnecessary attached of structure
Plus quality, the problem of necessary quality of existing building interior is used in TMD vibration insulating systems.
Technical scheme provided by the present invention is：It is a kind of to be held using furniture and household electrical appliance quality come the damper of vibration damping
Platform, using the furniture in building structure and household electrical appliance quality, designs a kind of cushion cap of use TMD damper principles, by furniture
And household electrical appliance are placed in formation TMD vibration insulating systems on this cushion cap.
It is a kind of using furniture and household electrical appliance quality come the damper cushion cap of vibration damping, the damper cushion cap includes cushion cap, rolling
Pearl slideway, cushion cap bearing, spring viscous damper and detachable spring；Cushion cap includes upper cushion cap and lower cushion cap, and the two table top is put down
OK, upper cushion cap is used to dispose furniture and household electrical appliance, and ground is fixed or be close to lower cushion cap by bearing；Upper cushion cap and lower cushion cap
Center is equipped with upper cushion cap center column casing of the circular port on circular port, upper cushion cap for protrusion, and the circular port of lower cushion cap is held under being
Platform center hole；Provided with circular ball slideway between upper cushion cap and lower cushion cap, ball slideway is fixed at lower cushion cap center hole, is rolled
Ball on pearl slideway is contacted with the upper cushion cap center column casing protruded；Upper cushion cap center column casing diameter is less than lower cushion cap center hole
Diameter；Three spring viscous dampers are disposed between upper cushion cap center column casing and the center hole of lower cushion cap and multiple dismountable
Spring；Spring viscous damper is fixedly connected by spring with viscous damper to be constituted；Viscous damper is by fluid cylinder, piston and piston
Bar is constituted；Fluid cylinder is the cylindrical container with inner chamber piston, fluid cylinder level；Spring viscous damper fluid cylinder is fixed in cushion cap
Stem medial wall of the tube, three cylinder ends are directed to the center of circle of cushion cap center column casing, and angle is 120 °；Spring viscous damping
The spring end of device is fixed on lower cushion cap center hole madial wall, spring viscous damper horizontal positioned, the viscous resistance of three springs
The fixing point trisection lower cushion cap center hole circumference of Buddhist nun's device；Detachable spring horizontal be installed on cushion cap center column casing side wall with
Between the wall of lower cushion cap center hole side, Pile-cap Rigidity is adjusted according to detachable number of springs is adjusted；Four cushion cap bearing connections
In lower cushion cap bottom surface, fix or contact to bottom surface.
The invention has the advantages that make use of in building essential furniture and household electrical appliance quality as tune
The quality of humorous mass damper (TMD), and rigidity is adjusted by detachable spring, so as to change the cycle, reach and do not increase knot
Unnecessary additional mass in structure, using existing necessary quality, carries out the purpose of TMD vibration dampings.
