The thin film type air damper has the advantages of high bearing ability, low rigidity, small size, low manufacturing cost and stable stopping process.
Description
Technical field
The present invention relates to a kind of diaphragm type air bump.
Background technique
Now, the means for vibration damping are a lot, have steel spring, rubber spring, pneumatic spring etc.But these means are in the face of large bearing capacity, and the requirement of little rigidity, but seems very clumsy, i.e. enable realization, and be also that cost is high, volume is large.
Summary of the invention
The object of this invention is to provide a kind of diaphragm type air bump, bearing capacity is large, stopping process is steady, solve that existing vibration damper exists for realizing vibration damping and high, the bulky problem of cost.
Technical solution of the present invention is:
A kind of diaphragm type air bump, comprises the film that flexible material makes, two stiffener plate be parallel to each other-and stiffener plate two, pipeline, container, adjustable restrictive valve, stop valve,
Film is located between stiffener plate-and stiffener plate two; Film separately or with stiffener plate-, stiffener plate two is formed with the confined space of receiving fluids jointly; Stiffener plate-or stiffener plate two are provided with passage, and confined space is communicated with the hydraulic power of the periodically variable liquid stream in exportable direction or air by passage, pipeline, adjustable restrictive valve; Stop valve is in parallel with adjustable restrictive valve;
Stiffener plate-, stiffener plate two two sides in opposite directions all can be divided into three regions: the region I contacted all the time with film or liquid; With film or liquid discontiguous region II all the time; Other region III; Region I is not communicated with region II; Film and stiffener plate-, stiffener plate two can adopt bonding or fix with flange screw, or only contacting.
Further, the both sides of film arrange respectively stiffener plate-, stiffener plate two, film is bonding with the stiffener plate being provided with passage or fixed by flange, screw, makes channel connection confined space.
Further, stiffener plate-or stiffener plate two are fixed with the object needing vibration damping, another stiffener plate is fixed on a stabilising surface.
The invention has the beneficial effects as follows: this kind of diaphragm type air bump, bearing capacity is large, and rigidity is little, and volume is little, and cost is low, and stopping process is steady.This kind of diaphragm type air bump, the principle utilizing film can bear very large pressure when radius of curvature is very little achieves very large bearing capacity, and it utilizes the gas principle that pressure change is very little when Volume Changes is very little, achieves very little rigidity.The principle that throttling is consumed energy is utilized again to achieve the steady of stopping process.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention;
Fig. 2 is embodiment's film structural representation bonding with stiffener plate two;
Fig. 3 is the structural representation that embodiment's film and stiffener plate two flange are fixed;
Wherein: 1-stiffener plate one, 2-stiffener plate two, 3-film, 4-pipeline, 5-stop valve, 6-adjustable restrictive valve, 7-container, 8-screw, 9-flange.
Embodiment
The preferred embodiments of the present invention are described in detail below in conjunction with accompanying drawing.
The stiffener plate 1 be parallel to each other by two, stiffener plate 22, to form with the film 3 that the non-leakage flexible material not easily extended is made, as Fig. 1, Fig. 3, stiffener plate 1, stiffener plate 22 two sides are in opposite directions respectively A` face, B` face, the distance in A` face, B` face is very little, be preferably <30mm, two stiffener plate can do the relative movement perpendicular to A` face.
A` face, B` face can be divided into three regions:
All the time the region I contacted with film 3 or liquid;
With film 3 or liquid discontiguous region II all the time;
Other region III.
Region I is not communicated with region II, film 3 is only tightly connected with stiffener plate in region I, the method connected is that bonding, flange 9 compresses and connects or only contact and not fixing, namely with the stiffener plate being provided with passage, in non-passage area, film 3 is bonding with stiffener plate, as Fig. 3, or compressed by screw 8, flange 9, as Fig. 2, make film 3 separately or jointly form confined space with stiffener plate, and film 3 and another stiffener plate can part bonding or only contact and do not fix, stiffener plate is moved perpendicular to A` face.
Can free bend with the discontiguous part of two stiffener plate, thus the volume of this enclosed space is variable, this enclosed space is by pipeline 4 and stop valve 5 or adjustable restrictive valve 6, be communicated with container 7, wherein be filled with the air of suitable pressure, stop valve 5 and adjustable restrictive valve 6 are in parallel, and all the other connections are series connection.Two stiffener plate one 1 and ground are fixed, and fix for one with needing the object of vibration damping.
Two stiffener plate and film 3 define an airtight space, and the air in confined space passes in and out this confined space through a passage.This kind of diaphragm type air bump, the principle utilizing film 3 can bear very large pressure when radius of curvature is very little achieves very large bearing capacity, and it utilizes the gas principle that pressure change is very little when Volume Changes is very little, achieves very little rigidity.The principle that throttling is consumed energy is utilized again to achieve the steady of stopping process.
The film 3 made with the non-leakage flexible material not easily extended and two stiffener plate be parallel to each other two sides are in opposite directions tightly connected, and space three formed is communicated with an enough large container 7 and is filled with pressurized air wherein, just constitutes a spring.The cross section of the edge of film 3 is semicircles of a radius=R, just larger pressure can be born when R is less. when the volume of described container 7 is enough large, the ratio of the volume-variation caused by the vibration of vibration damping object is just very little, and thus the change of pressure is just very little, thus reaches the object of vibration damping.
