Embodiments providing a kind of damper, see figures.1.and.2, including connector 1, connector 1 is used for and frame
Ceases to be busy cable connects, and connector 1 is fixed with elastic component 2, elastic component 2 is fixed with tup 3, when connector 1 vibrates, at tup
Under the effect of 3 inertia force, elastic component 2 can occur bending and deformation, and elastic component 2 is made by metal rubber material.
The damper that the embodiment of the present invention provides, owing to elastic component 2 is made by metal rubber material, therefore at elastic component 2
When occuring bending and deformation, the relative shift between the internal tinsel being wound around mutually of elastic component 2 is bigger so that fricative
Heat is more, so that the ability that the changes mechanical energy of cable is interior energy is strengthened by damper, and then improves cable vibration
Control effect；It addition, metal rubber material has low-density, corrosion-resistant, antioxidative advantage, thus extend damper
Life-span, reducing the quality of damper, also adapt to the severe chemical environments such as coastal area simultaneously, the scope of application is wider.
Make the rigidity of elastic component 2 less it should be noted that elastic component 2 is made by metal rubber material, so that anti-
Vibration hammer has a relatively low natural frequency of vibration, therefore with to blow air over the Karman vortex street vortex shedding frequency phase-difference produced on cable relatively big,
Thus avoid and produce resonance with cable；It addition, elastic component 2 is made the intensity also increasing elastic component 2 by metal rubber material,
Thus avoid elastic component 2 and rupture, and then extend the life-span of elastic component 2.
With reference to Fig. 1, connector 1 being provided with the first installing hole 4 in the first direction, described aerial cable may be disposed at the first peace
In dress hole 4, elastic component 2 is shaft-like, and arranges along described first direction, thus can be in the consistent feelings of moment of flexure suffered by elastic component 2
Shorten the length of elastic component 2 under condition, thus save elastic component 2 material in the case of elastic component 2 deflection is consistent, and then subtract
The little cost of damper.
In order to extend the life-span of cable further, in the present embodiment, connector 1 is connected with the middle part of elastic component 2, elastic component 2
Be respectively fixed at two ends with tup 3, and the quality of two tups 3 is equal so that damper generally symmetrical structure, thus
Avoid and penetrate the cable of the first installing hole 4 and bend, and then the edge friction avoiding cable and the first installing hole 4 causes
Disconnection problem, extend the life-span of cable the most further.
In above-described embodiment, tup 3 can weld with the end of elastic component 2, thus tup 3 is fixed on the end of elastic component 2
Portion, it is also possible to the second installing hole 5 is set on tup 3, then the end of elastic component 2 is fitted through and be located in the second installing hole 5,
Thus tup 3 is fixed on the end of elastic component 2；Owing to welding can cause stress to be concentrated, therefore the present embodiment is preferably at tup 3
On the second installing hole 5 is set, and the end of elastic component 2 fits through and is located in the second installing hole 5, to avoid stress concentration phenomenon；
Furthermore it is preferred that so setting also can be avoided reserving space between elastic component 2 and tup 3, thus avoid hydrops accumulated snow and cause
The problem that alleviates of tup 3 mass.
Concrete, seeing figures.1.and.2, connector 1 includes wire clamp 11 and connecting plate 12, and wire clamp 11 is fixed on connecting plate 12
One end, elastic component 2 is fixed on the other end of connecting plate 12, and the first installing hole 4 is arranged on wire clamp 11, thus can be by even
Elastic component 2 and wire clamp 11 are kept apart by fishplate bar 12, thus when avoiding elastic component 2 deformation, tup 3 interferes with cable, connect
The thickness of plate 12 is preferably 1～2mm, thus reduces the thickness of connecting plate 12 on the basis of ensureing connecting plate 12 structural strength
Degree, and then reduce the quality of damper.
The damper that the embodiment of the present invention provides is investigated, owing to wire clamp 11 is by connecting plate 12 and elastic component from amechanical angle
2 fixing connections, wire clamp 11 both sides are substantially independent of each other, and therefore with junction point for boundary, damper can be divided into two subsystems
System, each subsystem individually considers.This system can be simplified further: tup 3 is considered by rigidity, the most only count its quality with used
Amount, and it is elastic to disregard it；Its elasticity of elastic component 2 meter, disregards its inertia.
Fig. 3 is the mechanical model figure of damper, and wherein Y (t) is the cable excitation to damper, and m is the quality of tup 3, l
It is exported to the length of tup 3 from wire clamp 11 for elastic component 2.Under the excitation of Y (t), tup 3 will up-down vibration, and elastic component 2
Then alternating bending under the effect of alternation moment of flexure, in vibration processes, the structural damping of elastic component 2 can absorb vibrational energy constantly
Amount so that the amplitude of cable reduces, thus reaches the purpose of vibration control.
Preferably, wire clamp 11 is one-body molded with connecting plate 12, thus can remove the installation between wire clamp 11 and connecting plate 12 from
Connectivity problem, thus decrease the stress concentration phenomenon that assembling brings to a certain extent.
Connector 1 is preferably made by insulant, thus can avoid producing eddy current near cable, thus avoid cable
The problem that transmission losses increases.
Described insulant can be pottery, it is also possible to for composite, owing to pottery is more crisp, along with the increasing of the time of use
Long, the crackle in pottery can be gradually increased, final fracture, and the service life causing damper is shorter, it addition, the quality of pottery is relatively
Greatly, the quality also resulting in damper increases the weight of, and therefore in the present embodiment, preferred described insulant is composite, on the one hand can
Extend the service life of damper, on the other hand can reduce the weight of damper.
With reference to Fig. 2, the cross section of elastic component 2 is preferably circular, and i.e. elastic component 2 is cylindrical bar, compares other shapes, cylinder
The end of the shape bar amount of deflection when vibration is less, so that the bending deformation quantity of elastic component 2 is more stable, and then makes damper pair
The vibration control effect of cable is more stable.
The material of tup 3 is preferably structural steel, compares the material of other equal prices, and the density of structural steel is higher, thus
Can increase the quality of tup 3, and then the bending deformation quantity of elastic component 2 can be increased when connector 1 vibrates, increase line
The vibration control ability of cable；It addition, structural steel is difficult to get rusty, thus the quality of tup 3 can be avoided to alleviate, and then avoid line
The problem that the vibration control ability of cable reduces.
In sum, the damper that the embodiment of the present invention provides has good mechanical performance and resist chemical performance,
On care and maintenance, cost is extremely low, with little need for any later maintenance.
The above, the only detailed description of the invention of the present invention, but protection scope of the present invention is not limited thereto, and any
Those familiar with the art, in the technical scope that the invention discloses, can readily occur in change or replace, should contain
Cover within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with described scope of the claims.
