Abstract
The invention relates to an amplification and displacement type energy dissipater, which can be used for reducing the influence of small displacement or turning angle generated in a building or equipment. The energy dissipater comprises a dowel bar (1), displacement type damping material (2), a fixed ring (3), a rotating ring (4), a dowel plate (5) and a supporting bar (6), wherein, the fixed ring (3) is arranged outside the rotating ring (4), the displacement type damping material (2) is fixed at the contact position of the fixed ring (3) and the rotating ring (4), the fixed ring is fixed and connected with a second connecting hinged support (8), and the rotating ring is connected with a first hinged support through the dowel bar. When equipment components or building nodes generate relatively small displacement or turning angle under the function of an external force, the displacement or the turning angle drives the dowel bar to move, the movement of the dowel bar amplifies the displacement or the turning angle through the dowel plate and an axle with appropriate sizes, and represents the amplified displacement on the two relative movement surfaces of the damping material, to ensure the damping material to yield and consume energy.
Description
Technical field
The invention belongs to a kind of energy consumer that amplifies micro displacement or corner that has, can be used for reducing the influence that is produced in building or the equipment with less displacement or corner.
Background technology
The passive energy dissipation technology is mainly by setting up energy consumer or power consumption parts at some position of equipment or structure; for structure provides certain additional stiffness or additional damping; under external force, geological process or wind action mainly by the dissipate energy of input equipment or structure of power consumption parts; to alleviate the dynamic response of equipment, structure; thereby protect the safety of agent structure better, be a kind of effectively, safety, economy and the engineering cushion technique of maturation day by day.Energy-consumption shock-absorption device mainly contains metal energy consumer, friction energy dissipation device, viscoelastic damper, viscous energy consumer, the energy dissipation behavior of preceding two kinds of energy consumers is main relevant with the relative displacement at energy consumer two ends, be called displacement relationship type energy consumer (or hysteresis type energy consumer), the energy dissipation behavior of the two kinds of energy consumers in back is main relevant with the relative velocity at energy consumer two ends, is called velocity correlation type energy consumer.
Generally speaking, equipment or building are under external force, geological process or wind action, the relative displacement or the corner that produce between the structure different component are less, and existing displacement relationship type energy consumer all needs structure to have bigger relative displacement or corner just can be given full play to energy dissipation capacity, thereby has influenced the passive energy dissipation effect of energy consumer; Existing simultaneously energy-dissipating device integral body takies bigger architectural space, influenced the service efficiency of architectural space, and need complicated energy consumer support system, the support system rigidity of energy consumer influences the power consumption effect of energy consumer again, makes this type of energy-dissipating device be subjected to different restrictions in the application of reality.
Denomination of invention
The objective of the invention is to develop the displacement type energy-dissipating device of a kind of structure for amplifying displacement or corner, relative displacement that this energy consumer is less with the structure different parts or corner amplify according to the power consumption needs, make the energy dissipation capacity of displacement type power consumption material obtain the performance of fullest, the volume of energy consumer itself is less simultaneously, and then more effectively improve the anti-seismic performance of building or the vibration of control appliance, and influence the use of building interior space hardly.
To achieve these goals, the present invention has taked following technical scheme.Mainly include dowel bar 1, displacement type damping material 2, retainer plate 3, turning collar 4, force transmitting board 5, support bar 6 with fixedly connected first being connected hinged-support 7 and being connected hinged-support 8 of element of installation or building with second.Wherein, retainer plate 3 is arranged on the outside of turning collar 4 and with second to be connected hinged-support 8 fixedly connected, is fixed with displacement type damping material 2 at retainer plate 3 and turning collar 4 contacts site; It is hinged that one end of dowel bar 1 and first is connected hinged-support 7, and the other end and first connecting axle 9 are hinged, and first connecting axle 9 is fixedlyed connected with force transmitting board 5, and force transmitting board 5 is fixedlyed connected with turning collar 4; It is hinged that one end of support bar 6 and second is connected bearing 8, and the other end is fixedlyed connected with second connecting axle 10, and second connecting axle 10 passes the center of the turning collar 4 that is positioned on the force transmitting board 5, and turning collar 4 can rotate around second connecting axle 10.
Be pasted with displacement type damping material 2 at retainer plate 3 and turning collar 4 contacted surfaces.
Be provided with groove at retainer plate 3 and turning collar 4 contacted positions, displacement type damping material 2 is arranged in this groove.
Described displacement type damping material is macromolecular material, lead, mild steel.
Distance between first 9 and second 10 is 2～5 with the span of the ratio of retainer plate 3 inner surface radiuses.This ratio value is big more, and the displacement after the amplification is big more.According to the character of the power consumption needs of equipment or building and power consumption material, determine the size of this ratio.
The present invention can amplify the relatively little displacement between the different structure member or the corner the best power consumption displacement request according to the power consumption material, promptly with fixedly connected first being connected hinged-support 7 and being connected little displacement that hinged-support 8 bar structures produce or corner with second and being delivered to turning collar 4 of equipment or building by first 9, force transmitting board 5 and second 10, relative displacement between turning collar 4 and the retainer plate 3 is amplified, thereby make the displacement type damping material consume maximum energy, and then the wind that reduces the vibration of equipment or building structure shake reaction and earthquake response.The present invention has advantages such as volume is little, stable, manufacturing is simple, easy to maintenance, good endurance, is a kind of device of passive energy dissipation very efficiently.
