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, be specifically related to a kind of cartridge type metal-rubber shearing friction damper.
Background technology
As the dissipative cell of many Tall Frameworks, traditional Viscous fluid damper has had good energy-dissipating property, but its energy consumption effect when small vibration is out of shape is not obvious, and its use in engineering is restricted.The present invention proposes a kind of damper, it is mainly comprised of steel plate and metal-rubber piece, has the vibration reduction and cushioning performance of rubber, high-low temperature resistant, anticorrosive, storage life is unrestricted, solved rubber shock absorber in time, variations in temperature and environment pollution and aging technical problem; 1. the present invention can reduce vibration level.Simple structure of the present invention, when metal-rubber piece stress deformation, slippage between its filament phase mutual friction, wire, torsion have the effect of dry-friction damping, and the caused damping of frictional force between the inner infinitesimal spring contact of metal rubber material face also can be converted to vibrational energy heat energy and spread out rapidly, reduced vibration level, reduce the energy that structure self is born, thereby reach the object of vibration damping; 2. long service life of the present invention.Metal-rubber piece itself just have anti-high and low-temp, anticorrosive, be difficult for the features such as aging, intensity is high, shock resistance, life-span are long, can guarantee for a long time effectiveness in vibration suppression.Comprehensive above-mentioned advantage, metal-rubber damper is as the newcomer in dissipative cell, because its superior stress performance and energy-dissipating property can obtain application widely in many tall steel frames.
Summary of the invention
The object of the invention is for solving above-mentioned deficiency, a kind of cartridge type metal-rubber shearing friction damper is provided.
The object of the invention is to be achieved through the following technical solutions:
A kind of cartridge type metal-rubber shearing friction damper, comprise that the tight steel sleeve of upper semi-circle clevis, lower semi-circular clamp steel sleeve, two cartridge type metal-rubber pieces and two screw-type reinforcing bars, two cartridge type metal-rubber pieces are put in the cylinder of upper and lower two semicircle clamping steel sleeves formations, on each cartridge type metal-rubber piece, a screw-type reinforcing bar is set, upper and lower two semicircle cylinders that clamp steel sleeve formation connect with fastening bolt.
The present invention also has some technical characterictics like this:
1. the screw-type reinforcing bar outside described in applies axial pre tightening force with bolt and carrys out extrusion metal block rubber, thereby carries out the build-in connection of whole cartridge type metal-rubber shearing friction damper.
The present invention has following useful effect:
The cartridge type metal-rubber shearing friction damper that the present invention proposes is a kind of novel dissipative cell of many Tall Frameworks or other form of structure, there is initial stiffness large, small vibration distortion power consumption obviously, deformability is large, hysteresis loop is full, energy dissipation capacity waits well various advantages energy, is a kind of outstanding dissipative cell.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention;
Fig. 2 is decomposition texture schematic diagram of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated:
A kind of cartridge type metal-rubber shearing friction damper, comprise that the tight steel sleeve 1 of upper semi-circle clevis, lower semi-circular clamp steel sleeve 4, two cartridge type metal-rubber pieces 3 and two screw-type reinforcing bars 2, two cartridge type metal-rubber pieces 3 are put in the cylinder of upper and lower two semicircle clamping steel sleeves 1,4 formations, on each cartridge type metal-rubber piece 3, a screw-type reinforcing bar 2 is set, upper and lower two semicircle cylinders that clamp steel sleeve 1,4 formations connect with fastening bolt; Described screw-type reinforcing bar outside applies axial pre tightening force with bolt and carrys out extrusion metal block rubber, thereby carries out the build-in connection of whole cartridge type metal-rubber shearing friction damper.
Cartridge type metal-rubber piece is that the metal wire knitted of the spiral status opened with the stretching that certain method prepares quality is good, then uses cold punching technology moulding; The semicircle steel sleeve that clamps adopts common iron, opens some bolts hole, does the use connecting.Cartridge type metal-rubber piece is placed directly in the semicircle steel sleeve the inside that clamps; And with bolt, two semicircle steel sleeves that clamp are connected; Between cartridge type metal-rubber shearing friction damper metal-rubber piece and its accessory structure, by two, step up steel sleeve and carry out build-in with the extruding of intermediate thread reinforcing bar and be connected, there is no other connection measure.
Experimental results show that, the cartridge type metal-rubber shearing friction damper that the present invention proposes, traditional Viscous fluid damper is improved appropriately, by General Purpose Rubber is replaced by metal-rubber, can well improve the performance of traditional Viscous fluid damper, have small vibration distortion power consumption obviously, hysteresis loop is full, the advantage that energy-dissipating property is good.Can believe, once metal-rubber starts large-scale production application in China, will promote effectively the marketization application of the superior metal-rubber damper of this energy-dissipating property.
Claims (2)
1. a cartridge type metal-rubber shearing friction damper, comprise that the tight steel sleeve of upper semi-circle clevis, lower semi-circular clamp steel sleeve, two cartridge type metal-rubber pieces and two screw-type reinforcing bars, it is characterized in that: two cartridge type metal-rubber pieces are put in the cylinder of upper and lower two semicircle clamping steel sleeves formations, on each cartridge type metal-rubber piece, a screw-type reinforcing bar is set, upper and lower two semicircle cylinders that clamp steel sleeve formation connect with fastening bolt.
