Specific embodiment
Embodiment one: it is a kind of without add the multi-direction wide frequency domain of damper every vibration damping/shake device, comprising: the first steel
Plate 1, the second steel plate 2, third steel plate 4, the 4th steel plate 5, lamination support 3,1 lower section of the first steel plate is successively are as follows: the second steel plate 2 is folded
Layer support 3, third steel plate 4, the 4th steel plate 5；First steel plate 1 and the 4th steel plate 5 are oppositely arranged；Lamination support 3 and the second steel plate
2, third steel plate 4 constitutes viscoplasticity support；
The lamination support, which is superimposed by the 5th steel plate 6 with viscoelastic material layer, to be vulcanized；
Wherein, the upper surface of the 5th steel plate 6 is provided with the first serration 6-1 of protrusion, lower surface is provided with protrusion
The second serration 6-2；
First serration 6-1 mutually staggers corresponding with the raised 6-4 of the second serration 6-2 and groove 6-5, makes
Viscoelastic material layer between the serration of adjacent the 5th steel plate and the 5th steel plate it is horizontal have with vertical direction compared with
Big damping；
The quantity of first serration 6-1 and the second serration 6-2 are two, in the first adjacent zigzag
Returning plate 6-3 is provided between the end of protrusion 6-1, returning plate 6-3 is parallel with the 5th steel plate 6.
It is of the invention without add the multi-direction wide frequency domain of damper every vibration damping/shake device, mainly faced in invention
Following two problem.
First is that on vertical direction, in the prior art, the viscoelastic layer in viscoplasticity support do not generate it is shear-deformable, thus
It can not effectively consume energy in vertical direction, how so as to play the energy consumption effect of viscoelastic material layer.
Second is that in the horizontal direction, the energy consumption effect of viscoelastic material layer how is played, in the prior art, in horizontal force
Under power, steel plate may be detached from viscoelastic material layer, cause viscoelastic material layer that can not effectively realize shear energy dissipation；
For first problem, vertical shear-deformable, this problem andsolution of viscoelastic material layer, in existing skill
It is not related in art.As illustrated in figures 4-5, the design scheme of comparative example one, with reference to the theory of viscoelastic damper, adjacent
2 groups of shear components are set between five steel plates；Specifically, the construction of 1 group of shear component is as follows: in the upper of the 5th following steel plate
A steel plate is arranged in surface, and two steel plates are arranged in the lower surface of the 5th steel plate above and form two T shape restraining plates, two T shapes are about
Beam plate presss from both sides a steel plate and forms 1 group of shear component, and under the repeated action of vertical load, two T shape restraining plates generate phase with steel plate
To movement, so that viscoelastic material layer generation is shear-deformable.However, the viscoelastic material of viscoelastic damper is only arranged
Viscoelastic material layer is set between two T shape restraining plates and steel plate, and above scheme is directly applied into multidimensional every vibration damping/shake
In support, so that support loses vertical vibration isolation/shake function.
Even if viscoelastic material layer is filled in adjacent upper and lower steel plate, due to the length of T shape restraining plate and steel plate
It is longer, so that the rigidity of support is excessively high, influence vertical vibration isolation/shake function of support.
As shown in Figure 1, in order to guarantee that support has the function of preferable vertical vibration isolation/shake, viscoelastic material layer and the 5th steel
Plate is arranged alternately, and the two will have biggish ratio of height to thickness, such as 3-5；The rising height of the 5th steel plate upper and lower surfaces is not yet simultaneously
Can be as the scheme of comparative example 1, to meet every the requirement of damping/vibration support vertical rigidity, i.e. the 5th steel plate is prominent comprising zigzag
Play the thickness for being no more than viscoelastic material layer at the maximum cross-section with returning plate, it is preferred that no more than the thickness of viscoelastic material layer
The 1/2 of degree.And under vertical motion effect, the protrusion composition steel plate of the 5th steel plate upper and lower surfaces and erecting for viscoelastic material layer
To shear surface.And in order to improve the shear energy dissipation of viscoelastic material layer, innovative proposition setting returning plate is wanted to meet this
It asks.
For Second Problem, in order to guarantee the horizontal distortion of the 5th steel plate and viscoelastic material layer, by the surface of protrusion
It is set as zigzag and returning plate, the faying face between steel plate and viscoelastic material layer can be prevented to be detached from, so that the 5th steel
Under the effect of horizontal reciprocating power, shear surface is changed into viscoelastic material layer by the faying face of the two for plate and viscoelastic material layer
Section, so that the horizontal energy consumption for improving support is horizontal.
Embodiment two: the direction of horizontal vibration is arbitrary, and higher in order to guarantee to have on any level direction
The direction design of damping, the protrusion of the 5th steel plate is as follows: by the first serration 6-1 and the second serration 6-2
It is shaped to arc-shaped or round setting；The quantity of first serration 6-1 of the 5th steel plate is 2 articles or more,
In, the first serration 6-1 is arranged in parallel, and the center of circle is located at same point；Second serration 6-2 of the 5th steel plate
Quantity be 2 or more, wherein the second serration 6-2 is arranged in parallel, and the center of circle is located at same point.
In the quantity of the first serration and the second serration respectively at 3 or more when, from the 5th steel plate edge
Onto center position, the spacing of the first adjacent serration is gradually increased, the spacing of the second adjacent serration by
It is cumulative big.
The preferred embodiment of present aspect has already been described in detail above, it is understood that having read of the invention above-mentioned say
After awarding content, those skilled in the art can make various modifications or changes to the present invention.Such equivalent forms equally fall into this Shen
It please be in the protection scope of the appended claims.
