Abstract
An improved shearing viscoelasticity damper belongs to the shearing viscoelasticity damper technical field and is used to improve the performance of a shearing viscoelasticity damper through novel arrangement and combination. The damper comprises an upper steel plate layer, a middle steel plate layer, a lower steel plate layer and viscoelasticity material layers arranged between the steel plate layers, and realizes the following improvements: steel plate layers and corresponding elastic material layers are respectively arranged between the middle steel plate layer and the upper steel plate layer as well as between the middle steel plate layer and the lower steel plate layer at the same time; moreover, the elastic material layers are casting polyurethane elastic bodies. The novel arrangement structure provided by the utility model is a better arrangement structure selected after repeated experiment according to a scientifically designed screening method; tests show that the arrangement structure can remarkably improve the stress proportionality and stability of the shearing viscoelasticity damper; therefore, the utility model has the remarkable advantages of high cost performance, strong economic applicability and higher safety and reliability, and is suitable to be used as an energy-consuming damping vibration reduction damper installed in an engineering structure.
Description
Technical field
The utility model relates to multiple layer shear viscoelasticity damper, belongs to multiple layer shear viscoelasticity damper technique field.
Background technique
The shear viscoelasticity damper is the combination of constraint steel plate and viscoelastic material interphase distribution, steel plate and viscoelastic material are combined into integral body through vulcanizing treatment, in power effect lower steel plate generation relative displacement repeatedly, make viscoelastic material produce reciprocal shear deformation, thus power consumption.Traditional arrangement form of shear viscoelasticity damper is: mesosphere and upper and lower skin are steel plate, clamping viscoelastic material layer between the steel plate.In viscoelastic damper, parameters such as the storage elastic modulus of visco-elastic damping material, loss elastic modulus and fissipation factor have very big influence to the performance of viscoelastic damper, but the arrangement form of steel plate and viscoelastic material also can not be ignored the influence of shear viscoelasticity damper.Above-mentioned traditional three-ply plate adds the shear viscoelasticity damper of two-layer visco-elastic damping material arrangement form, the aspect of arranging is few, it in view of stress equalization, stability the best combination of arranging, still there is the very big possibility that strengthens shear viscoelasticity damper performance by the different arrangement form of experiment sieving, for this reason, the research that should carry out this aspect is explored.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of improved shear viscoelasticity damper, to strengthen the performance of shear viscoelasticity damper by the combination of newly arranging after improving.
The alleged problem of the utility model realizes with following technological scheme:
A kind of improved shear viscoelasticity damper, the viscoelastic material layer that upper, middle and lower steel plate layer and steel plate interlayer are arranged in the formation, its improvement is, sets up the steel plate layer respectively between light plate layer and upper and lower steel plate layer, the corresponding viscoelastic material layer of setting up in steel plate layer both sides of setting up simultaneously.
Above-mentioned how improved shear viscoelasticity damper, described viscoelastic material layer are casting type polyurethane elasitic layer.
The utility model provides sets up steel plate layer, and corresponding new arrangement form of setting up viscoelastic material layer between light plate layer and last lower steel plate layer, it is screening method according to scientific design, the preferable arrangement form that the experience test of many times screens, after tested, this arrangement can significantly improve the stress equalization and the stability of shear viscoelasticity damper, therefore makes to the utlity model has remarkable superiority such as cost performance height, economic serviceability is strong, safety is more reliable; When viscoelastic material layer is the casting type polyurethane elastomer, because the casting type polyurethane elastomer has advantages such as high hardness, high strength, high elasticity, high anti-oxidation, highly corrosion resistant, high wear resistance, can further improve bearing capacity of the present utility model and passive energy dissipation (shake) performance, suit to install and use as the passive energy dissipation damping utensil in the engineering structure.
Description of drawings
Fig. 1 is the utility model structural representation.
The component label is respectively in the accompanying drawing: 1-holds steel plate, 2-light plate layer, the upper and lower steel plate layer of 3-, 4-viscoelastic material layer, 5-steel plate layer.
Embodiment
Consult accompanying drawing 1.As shown in the figure, set up steel plate layer 5 respectively between light plate layer 2 and upper and lower steel plate layer 3, middle steel plate layer 2 is connected with the end steel plate 1 of left with upper and lower steel plate layer 3, and the two steel plate layers of setting up 5 are connected with right-hand end steel plate 1.After setting up two steel plate layers 5, viscoelastic material layer 4 two-layerly becomes 4 layers by original.Viscoelastic material layer 4 can adopt casting type polyurethane elasitic layer.
Claims (2)
1. improved shear viscoelasticity damper, the viscoelastic material layer that upper, middle and lower steel plate layer and steel plate interlayer are arranged in the formation, it is characterized in that, between light plate layer [2] and upper and lower steel plate layer [3], set up steel plate layer [5] respectively, simultaneously the corresponding viscoelastic material layer [4] of setting up.
2. improved shear viscoelasticity damper according to claim 1 is characterized in that, described viscoelastic material layer [4] is a casting type polyurethane elasitic layer.
