Abstract
The utility model discloses a memorial alloy rubber imitation metallic vibration damper. The existing memorial alloy vibration damper is lack of damping performance. The memorial alloy rubber imitation metallic vibration damper comprises three connecting elements (1), wherein rubber imitation metallic elements (2) made of shape memorial alloy are connected between adjacent two connecting elements; and shaft cores of the rubber imitation metallic elements are provided with two adjacent connecting elements which are connected with a dowel steel (3). The utility model is used as a vibration damper in engineering structures.
Description
Technical field:
The utility model relates to a kind of memory alloy and intends the rubber-metal vibration damper.
Background technique:
The various countries scholar is making great efforts to explore the application of marmem (Shape Memory Alloy-SMA) super elastic characteristics in the vibration control field at present.From result of study, various forms of marmem SMA vibration dampers, the viscoelasticity vibration damping structure of other big damping relatively, damping characteristic still is short of.
The plan rubber-metal preparation process that development in recent years is got up is to be made by common Stainless Steel Wire or iron wire, and its manufacture process is first with the wire coiled, and then mould compression moulding is put in stretching.Because intending the rubber-metal vibration damper is made up of a lot of little springs, do the time spent being subjected to external force, the friction that mutual slippage between the little spring produces must consume portion of energy, therefore, when having possessed metal vibration damping advantage, can improve the damping and amortization characteristic again, shared spatial volume is little, the vibration damper shape freedom of making, this plan rubber preparation process has bigger application potential.
So utilize the super elastic characteristics of SMA, use the preparation process of intending rubber-metal, be made into the SMA silk and intend the rubber-metal element, and can utilize its design, making high damping vibration attenuation device.
Summary of the invention:
The purpose of this utility model provides a kind of memory alloy and intends the rubber-metal vibration damper, and the preparation process of utilizing the super elastic characteristics of marmem and intending rubber-metal is implemented in and alleviates on the engineering structure or avoid vibration hazard.
Above-mentioned purpose realizes by following technological scheme:
Memory alloy is intended the rubber-metal vibration damper, its composition comprises: three links, connect the plan rubber-metal element that marmem is made between described two adjacent links, the axle center of described plan rubber-metal element has dowel bar and connects two adjacent links.
The beneficial effects of the utility model:
It is its special hysteretic energy performance that the utility model has utilized the super elastic characteristics of marmem SMA, marmem is compared with common material has lot of advantages: anti-corrosion capacity, antifatigue effect preferably, bigger recoverable strain, temperature and the range between a frequency used in engineering have stable mechanical property or the like.These characteristics make this product have the favorable damping performance.
The plan rubber-metal element that the memory alloy that the utility model adopts is made can well increase damping, is applied on the engineering structure, can alleviate or avoid vibration hazard.
Description of drawings:
Accompanying drawing 1 is the cross-sectional view of this product.
Embodiment:
Embodiment 1:
Memory alloy is intended the rubber-metal vibration damper, its composition comprises: three links 1, connect the plan rubber-metal element 2 that marmem is made between described two adjacent links, the axle center of described plan rubber-metal element has dowel bar 3 and connects two adjacent links.
Utilize the super elastic characteristics of marmem SMA, use the preparation process of intending rubber-metal, be made into the SMA silk and intend the rubber-metal element, design, making high damping vibration attenuation device are applied on the engineering structure, can alleviate or avoid its vibration hazard.
Utilize superelasticity SMA silk to make and intend the rubber-metal element, design vibration damping equipment: intend the rubber-metal element by two groups of identical SMA of performance and (realize both collaborative works as damping member-exchange device structural design but the SMA that symmetrical configuration distributes intends the rubber-metal element, be for dissipation energy more in the vibration processes, increase damping) and link, dowel bar is formed, when in engineering structure, using, vibration force is intended on the rubber-metal element by two SMA that link and dowel bar are delivered to the energy that can dissipate, power consumption by SMA plan rubber-metal realizes damping effect.In addition, this device development also can and spacingly design consideration to bearing capacity.
