Description
Technical field
The utility model belongs to metal material/shake control/noise abatement/structure technical field, especially a kind of base
In memorial alloy (SMA) and for the energy-consumption damper of stereo garage damping noise reduction demand.
Background technology
With the fast development of China's economy and the raising of people's lives axial direction, private car is very universal so that people
Trip it is very convenient.In terms of development trend, private car ownership can still remain high in future, result in motor vehicle and possess
Measure the excessively contradiction between the wretched insufficiency of parking stall.The ratio on China's automobile guarantee-quantity and parking stall is only 5 at present:1, and vehicle
The rational proportion of position and car ownership should be 1.2:1.Currently, many communities are all extending underground garage, although can be appropriate
Alleviate current contradiction, but its civil engineering input cost is relatively high, economic benefit is bad.Based on this present situation, the construction of stereo garage
With promoting in order to solve a main method of " parking difficulty ".
Although stereo garage is haveed many advantages, such as, stereo garage actually build and extension process in there is also
Many problems.Since current stereo garage is mainly all made of steelframe structure, for the stereoscopic vehicle of multilayer (more than 3 layers) structure
For library, stability is poor, wind-engaging shake, earthquake and more serious from the influence of shake, long-term and become to have stereoscopic garage structure
The risk that shape is even collapsed；Garage is in running simultaneously, and the vibrations generated by motor will produce prodigious noise, at some according to building
And in the garage built, the contact that vibrating noise can be by steelframe structure with flooring passes to building, and to living, personnel wherein cause
Detrimental effect.Therefore for stereo garage vibrations control be one can not be ignored the problem of.
To weakening or eliminating influence of the vibrations to stereo garage, it is crucial to start with from structure quake control.Structure is shaken
Dynamic control is divided into passive control system, active control system, semi-active control aystem and hybrid control system four major types.Passively
The design philosophy of control is that (weakening), isolation (base isolation), transfer (absorbing damping), (energy consumption subtracts for consumption using directly reducing
Shake) the methods of energy achievees the purpose that reduce structural vibration.The memorial alloy energy-consumption damper that this programme proposes passively controls then
Belong to consumption energy and reaches the method for reducing structural vibration.
Marmem (Shape Memory Alloy, SMA) is a kind of novel conjunction by extensive concern nearly ten years
Golden material has unique pseudo- (super) elastic property and high damping characteristic, and using these characteristics, which can be widely used
In Structural Energy Dissipation damping, except in the fields such as make an uproar.
Super-elasticity refers to being loaded to the SMA in austenite phase, and alloy starts to work in elastic range, works as stress
When more than elastic limit, stress-induced martensitic phase transformation, into super-elasticity platform；After unloading, make deformation through martensite reverse transformation
Restore, as shown in Figure 1.During Load-unload, SMA absorbs big energy.The maximum of SMA can recovery strain be up to 6~
10%.
In the design of marmem damper, generally all can SMA alloy silk prestretching first be extended into super-elasticity platform
At (Fig. 1), maximumlly it can reach the maximized purpose of energy-dissipating and shock-absorbing using superelastic properties in this way.
Utility model content

Draw bar on pipe is conducted to B alloy wire, makes wherein four in shape is stretched, in addition four are in contraction-like, back and forth reach consumption with this
It can effect.
This energy-consumption damper may be mounted on stereo garage steelframe structure, play the role of damping；In addition for according to building and
It builds or the stereo garage in building, damper may be mounted on the contact surface of garage framework and flooring, play damping drop
The effect made an uproar.
The side of installing and using of energy-consumption damper based on memorial alloy (SMA) and for stereo garage damping noise reduction demand
Method：
A. this damper is applicable to the energy-dissipating and shock-absorbing of multilayer (3 layers or more) stereo garage.The framework of stereo garage is higher,
It is stronger by wind-force, earthquake and the vibration effect generated that works from motor.Simultaneously in order to save space, for multiple-layer stand
For body garage, surrounding is difficult to have vacant lot to install stability maintenance device for it again, so the stability and anti-vibration of stereo garage framework
Performance must be good enough, and it is difficult to accomplish to rely solely on steelframe structure itself.
Damper in this programme may be mounted at lower part (1,2 layers of bottom or the inverse, depending on specific layer of garage steelframe structure
Depending on number), it is installed in a manner of tiltedly putting, as shown in Figure 6.When external shock come it is interim (wind shake, earthquake, what mechanical equipment generated
Vibrations etc.), framework generates small deformation, and damper acts at this time, and the stretching through B alloy wire and compression will shake
Energy consumes, and achievees the purpose that damping.
B. in order to save the area, more and more stereo garages can be selected according to Lou Erjian at present, or be leaned against on the exterior wall in building,
Or it build in building.No matter in the form of what kind of, during stereo garage is run, the vibrations that generate can by with floor (face)
Contact reach in building, and generate noise belong to low frequency noise, penetrance is extremely strong, in building personnel work rest produce
Prodigious influence.For the stereo garage according to Lou Erjian, multiple dampers can be installed in the junction in garage and building, to subtract
The noise of weak shock movable property life, as shown in Figure 7.
C. in addition to this, which equally may be mounted at the junction of vehicle-carrying plate and cable wire, with this eliminate cable wire because
The noise that generates for vibrations and the stability for safeguarding vehicle-carrying plate.
The utility model is the damping effect based on damper to achieve the effect that safeguard framework stabilization and eliminate noise.
Therefore optimum implementation should be multidirectional installation damper on framework bottom and building contact surface, be maximized to reach
Elimination vibrating noise purpose.In addition this damper can also be installed on the cable wire for promoting automobile, for realizing vehicle-carrying plate
Stabilization and noise control.
The above is preferred embodiments of the present invention, it is noted that for the ordinary skill of the art
For personnel, the improvement made without departing from the principle of this utility model also should be regarded as the protection model of the utility model
It encloses.
