Abstract
The invention provides a drum type metal rubber shear friction damper which comprises an upper semicircular clamping steel sleeve, a lower semicircular clamping steel sleeve, two drum type metal rubber blocks and two threaded steel bars. The two drum type metal rubber blocks are placed in a drum formed by the upper semicircular clamping steel sleeve and the lower semicircular clamping steel sleeve, each threaded steel bar is arranged on the corresponding drum type metal rubber block, and the upper semicircular clamping steel sleeve and the lower semicircular clamping steel sleeve are connected with each other by fastening bolts to form the drum. The drum type metal rubber shear friction damper has the various advantages that the drum type metal rubber shear friction damper is high in initial stiffness and deformation capacity, obvious in small-vibration deformation energy dissipation effect and good in energy dissipation capacity, and is an excellent energy dissipation element, hysteric curves are full, and the like.
Description
Technical field
The present invention relates to technical field of structural engineering, and in particular to a kind of drum type metal rubber shear friction damper.
Background technology
Used as the dissipative cell of multi ＆ tall steel frame, traditional Viscous fluid damper is provided with good energy-dissipating property, but
It is that its energy consumption effect when small vibration deforms is not but obvious so as to which the use in engineering is restricted.The present invention is proposed
A kind of damper, it is mainly made up of steel plate and metal-rubber block, the vibration reduction and cushioning performance with rubber, high-low temperature resistant, anti-corruption
Erosion, storage life is unrestricted, solve rubber shock absorber with time, temperature change and environmental pollution aging technical problem；
1. the present invention can reduce vibration level.Simple structure of the present invention, when metal-rubber block stress deformation, its filament mutually rubs
Sliding, effect of the torsion with dry-friction damping between wiping, wire, and the infinitesimal spring contact of metal rubber material inside
Vibrational energy can also be converted to heat energy and be spread out rapidly by the damping caused by frictional force between face, reduce vibration
Magnitude, reduces the energy that structure itself is born, so as to reach the purpose of vibration damping；2. long service life of the present invention.Metal-rubber block
The features such as inherently having anti-high and low-temp, high anticorrosive, non-aging, intensity, shock resistance, life-span length, can for a long time ensure vibration damping
Effect.Summary advantage, metal-rubber damper as the newcomer in dissipative cell, due to its superior stress performance with
Energy-dissipating property can be widely applied in multi ＆ tall steel frame structure.
The content of the invention
The purpose of the present invention is to solve above-mentioned deficiency, there is provided a kind of drum type metal rubber shear friction damper.
The purpose of the present invention is achieved through the following technical solutions：
A kind of drum type metal rubber shear friction damper, including the tight steel sleeve of upper semi-circle clevis, lower semi-circular clamping steel
Sleeve pipe, two drum type metal rubber blocks and two screw thread steel bars, two drum type metal rubber blocks are put in upper and lower two pieces of semicircles
In clamping the cylinder that steel sleeve is constituted, a screw thread steel bar, upper and lower two pieces of semicircles are set on each drum type metal rubber block
The cylinder for clamping steel sleeve composition is connected with fastening bolt.
The present invention also has so some technical characteristics：
1. the screw thread steel bar outside described in applies axial pre tightening force to extrude metal-rubber block with bolt, whole so as to carry out
The build-in connection of individual drum type metal rubber shear friction damper.
The present invention has following beneficial effect：
Drum type metal rubber shear friction damper proposed by the present invention is multi ＆ tall steel frame or other structures form
A kind of new dissipative cell, big with initial stiffness, small vibration deformation power consumption is obvious, and deformability is big, and hysteresis loop is satisfied
Full, energy dissipation capacity waits well various advantages energy, is a kind of outstanding dissipative cell.
Description of the drawings
Fig. 1 is the overall structure diagram of the present invention；
Fig. 2 is the decomposition texture schematic diagram of the present invention.
Specific embodiment
Below in conjunction with the accompanying drawings the present invention is further illustrated：
Embodiment 1
A kind of drum type metal rubber shear friction damper, including tight steel sleeve 1, the lower semi-circular clamping steel of upper semi-circle clevis
4, two drum type metal rubber blocks 3 of sleeve pipe and two screw thread steel bars 2, two drum type metal rubber blocks 3 are put in upper and lower two and half
Circle is clamped in the cylinder that steel sleeve 1,4 is constituted, and a screw thread steel bar 2 is arranged on each drum type metal rubber block 3, upper and lower
Two pieces of semicircle cylinders for clamping the composition of steel sleeve 1,4 are connected with fastening bolt；Applied with bolt in described screw thread steel bar outside
Plus axial pre tightening force is extruding metal-rubber block, so as to the build-in for carrying out whole drum type metal rubber shear friction damper connects
Connect.
Embodiment 2
Drum type metal rubber block is the metal wire knitted of the spiral status for being opened the stretching that quality is prepared with certain method
It is good, then it is molded with cold punching technology；Semicircle clamps steel sleeve and adopts common iron, opens certain amount bolt hole, does and connects
It is used.Drum type metal rubber block is placed directly in semicircle clamping inside steel sleeve；Two semicircles are clamped steel bushings by blending bolt
Pipe connects；Between drum type metal rubber shear friction damper metal-rubber block and its accessory structure by two pieces step up steel sleeve with
The extruding of intermediate thread reinforcing bar carries out build-in connection, without others connection measure.
It is demonstrated experimentally that drum type metal rubber shear friction damper proposed by the present invention, enters to traditional Viscous fluid damper
Row is suitably modified, and by the way that General Purpose Rubber is replaced by metal-rubber, can be very good the property for improving traditional Viscous fluid damper
Can, obvious with small vibration deformation power consumption, hysteresis loop is full, the good advantage of energy-dissipating property.It is believed that metal-rubber is once
Start large-scale production application in China, should by the marketization of the metal-rubber damper for effectively promoting this energy-dissipating property superior
With.
