Movable Cultural Relics are important component parts of world cultural heritage, have extremely important culture, historical value, protect significant.To the protection of these historical relics, not only there are fire prevention, antitheft requirement, also should there is shockproof requirement.A large amount of earthquakes show, the floating historical relic of putting is 3～4 while spending in intensity of earthquake, just likely produces heavy damage.Due to the unpredictable and huge destructiveness of earthquake, make these historical relics take that precautions against earthquakes are extremely urgent timely and effectively.
From the floating Development Status of putting antique vibration isolation device of collection; domestic aspect wretched insufficiency in this regard, and external aspect as the countries such as Japan, the U.S., Italy generally promote the use of dissimilar antique vibration isolation device with realization the historical relic based on advanced technology anti-vibration protected.The dissimilar shock-proof devices such as roller type, roller type, ball type, slide block type, friction pendulum are researched and developed, the dissimilar shock insulation materials such as pneumatic spring, constant force spring, magnetite, marmem are applied, and make the DEVELOPMENT PROSPECT of antique vibration isolation device wide.But from the isolating affection of antique vibration isolation device, realize simple structure, little volume, low conduction than (ratio of the response acceleration peak value of historical relic and input seismic waves acceleration peak value) and avoid vertically waving, and guaranteeing that reliability, the durability of shock-proof device are still an important problem.
Existing antique vibration isolation device is mostly take horizontal seismic isolation as main, and vertical seismic element often accounts for critical role.From horizontal restoring force parts angle, traditional spring needs vertical double-deck setting party can realize level arbitrarily to shock insulation.Curved surface roller based on gravity restoring force or roller unit are easy to the problem that generation causes parts to fly out because horizontal seismic force is excessive.From vertical restoring force parts angle, traditional spring is because natural bow is excessive and easily produce vertical buckling problem, and parts complex structure, occupies vertical direction spatial larger.Therefore, needs research and development manufacture is easy, mechanism clear and definite, the multidimensional historical relic damping device of successful.
Summary of the invention
Existing antique vibration isolation device is mostly take horizontal seismic isolation as main, and vertical seismic element often accounts for critical role.From horizontal restoring force parts angle, traditional spring needs vertical double-deck setting party can realize level arbitrarily to shock insulation.Curved surface roller based on gravity restoring force or roller unit are easy to the problem that generation causes parts to fly out because horizontal seismic force is excessive.From vertical restoring force parts angle, traditional spring is because natural bow is excessive and easily produce vertical buckling problem, and parts complex structure, occupies vertical direction spatial larger.Based on this, the present invention attempts to address the above problem by the research and development of adjustable pendulum-type historical relic low frequency damping device.
For achieving the above object, the technological scheme that the present invention takes is a kind of adjustable pendulum-type historical relic low frequency damping device, comprises connecting rod, toughened glass case, anchor bolt, adjustable counterweight piece, lower link, belleville spring, outer showcase; Wherein, described upper connecting rod one end and described outer showcase are hinged, and the described upper connecting rod the other end and described toughened glass case are hinged; Described toughened glass case is placed the fixing adjustable counterweight piece of the described anchor bolt of Cultural Relic Bureau; Described lower link one end and adjustable pouring weight are hinged, and the lower link the other end and described belleville spring are hinged; Described outer showcase limits described belleville spring Horizontal displacement.
Described upper connecting rod and lower link, select the material that lightweight and intensity are high, as metal-base composites; Upper length of connecting rod and lower link length ratio are greater than 2.
Described adjustable counterweight piece, material selection lead alloy, zinc alloy, cast iron, described adjustable counterweight block length is wide identical with described toughened glass case, described adjustable counterweight piece is fixed on described toughened glass case bottom with described anchor bolt, can change quality size by changing described adjustable counterweight number of blocks.
Described toughened glass case uses full tempered glass, the built-in friction bedding of described toughened glass case.
Described belleville spring can change rigidity by changing reed quantity.
In the time that shock insulation cultural relic cabinet is subject to geological process, belleville spring is stretched and is compressed, and resists the geological process of vertical direction, toughened glass case and upper connecting rod and lower link are hinged, and swing in the horizontal direction with low frequency, resist the geological process of substantially horizontal, and then reach the object of shock insulation.
The present invention adopts single pendulum and puts vibrating isolation system principle in parallel, toughened glass case and mass-adjustable piece quality and be m, toughened glass case upper end with long be L

2, belleville spring initial compression amount is Δ L, and system is in the time of equilibrium position, and system stiffness is:
If make K (0)=0,
When
Time, vibrating isolation system in the horizontal direction rigidity is 0, vibrating isolation system reaches low frequency vibration isolation effect, along with L
