Background technology
Under the sharp pounding effect, will bring huge destruction to structure, therefore study the important topic that safer, more economical reliable building structure vibration-isolating system becomes the structural seismic field.Although present rubber shock absorption support can reduce to shake the destructiveness to building structure to a certain extent, but still can not meet the needs of production, so a kind of research of efficient shock mount is very significant.
The advantages such as now, the General Purpose Rubber bearing is the seismic isolation technology of comparative maturity, and is good owing to its isolating affection, that damping performance is remarkable are used widely in recent years.But, along with increasing of scientific experiment and engineering practice, when neoprene bearing is obtained good damper effect, also expose many defectives.At present the modulus of deformation of General Purpose Rubber bearing is too low, and the large and large deformation rear support distortion of horizontal distortion is difficult to reset; Damping is less, energy dissipation capacity is poor, and especially the relative deformation of superstructure and Seismic Isolation of Isolation Layer is larger; Also there are easily the problems such as aging, perishable and shock insulation frequency band is narrower in the General Purpose Rubber bearing, can not realize the effective damping of the vibration wave of multifrequency feature, isolating affection, is difficult to the intellectuality of implementation structure damping, shock insulation.Marmem has a lot of distinguished special natures as a kind of brand-new functional material, has obtained a large amount of application in scientific research and practical application.Its key property shape memory effect and superelastic effect are widely used in the cushion technique field especially.Marmem has extremely strong distortion recovery capability, and the overstrain that produces in the vibrations distortion can comparatively fast be recovered, simultaneously, marmem is because have superelastic effect, larger damping can be provided, consume the energy that vibration is transmitted, thereby strengthen the shock resistance of entire system.In addition, marmem also has the advantages such as antifatigue, resistance to torsion and biocompatibility, and is stronger to the adaptive capacity of working environment.But the price of marmem is higher at present, and therefore, the research of safer, more economical reliable New Shape Memory Alloys damping, earthquake isolating equipment has important practical significance.
Based on above situation, the present invention is directed to the defective that present General Purpose Rubber bearing exists, the characteristic in conjunction with super elastic shape memory alloy and power consumption property proposes a kind of novel shape memory alloy damping energy dissipating support.The advantage of this device is a series of shortcomings that overcome the General Purpose Rubber bearing, utilizes super-elasticity and the power consumption property of marmem, has realized the multiple dimension shock-proof of structure, has improved isolating affection.
Summary of the invention
The object of the present invention is to provide and a kind ofly improve vertical direction anti-pulling ability and price is low, practical, the structural damping shock insulation energy dissipating support of marmem easy for installation.
The object of the present invention is achieved like this: the present invention is by rubber element (1), upper strata junction steel plate (2), lower floor's junction steel plate (3), shape-memory alloy wire bundle (4), smooth torus (5) and pulley (6) form, rubber element (1) and upper strata junction steel plate (2) are connected 3 with the lower floor junction steel plate) be connected, lower floor's junction steel plate (3) is connected with fixed reference system, upper strata junction steel plate (2) is connected with carrier, smooth torus (5) evenly distributes and is welded on upper strata junction steel plate (2) and the lower floor's junction steel plate (3), pulley (6) is enclosed within on the smooth torus (5), shape-memory alloy wire bundle (4), pulley (6) is arranged in around the bearing by smooth torus (5).
Shape-memory alloy wire bundle (4) is the twisted wire of being made by shape-memory alloy wire.
Marmem adopts the NiTi memorial alloy.
