Specific embodiment
As shown in Figure 1, air damping spring arrangement, be successively arranged several mutually isolated cavity 11 in cylinder body 1, both ends by
End cap 2 is closed, to form several airtight chamber in cylinder body 1.
Air bag 3 and piston 4 are equipped in cavity 11,3 one end of air bag fits in end cap 2.Piston rod 5 is through end cap 2 and piston 4
It is connected and fixed, piston 4 is made to fit always with 3 other end of air bag.Piston rod 5, which is located at 1 outboard end of cylinder body, is equipped with connector 6.
The utility model is fixed between two structure component of thing (between such as steel construction top cover and roof truss) or bridge pad by connector 6
It is interior, by piston rod 5 to the promotion compressing gasbag 3 of piston 4, reduce the gas volume in air bag 3, temperature increases, air pressure increases
Greatly, to generate biggish reaction force to piston 4, and then piston rod 5 is made to generate reply trend, forms the longitudinal section of cylinder body 1
Horizontal stiffness on direction, to avoid biggish horizontal displacement is generated between structure component of thing or between support movable surface and pedestal.Together
When, 4 side wall of piston matches with 11 inner wall of cavity, in 3 contraction process of air bag, rubs and generates between 11 inner wall of piston 4 and cavity
The heat that gas is pressurized and generates in heat, this partial heat and air bag 3 can be scattered and disappeared by cylinder body 1, to realize energy dissipating
(damping) damping.
Cylinder body 1 uses heat-conducting.It is preferred that aluminum alloy material is used, convenient for the rapid export of heat in cylinder body 1, and it is resistance to
Mill, quality are light and handy.
Air bag 3 uses flexible high molecular material.So as to the biggish compressing force of the transmitting of piston rod 5 be born, larger
Still there is preferable toughness and elasticity under deformation.The toughness of air bag 3 has bigger compression ratio compared with spring structure, to produce
Raw bigger damping energy dissipation is to improve damping effect.
It is sealed with compressed air in air bag 3, horizontal rigidity can be adjusted in the initial pressure by adjusting compressed air.
The length ratio of compressing gasbag 3 and cavity 11 is not less than 2:3.The horizontal stiffness as possessed by the utility model and subtract
Shock stability derives from the contraction of air bag 3 caused by the interaction of piston rod 5 and air bag 3, thus must ensure that air bag 3 has one
Fixed initial pressure and sufficient contraction range.
Pressure element is used as using air bag 3, is had the advantage that
1. compared with existing Ordinary Compression spring have biggish compression ratio (Ordinary Compression amount of spring compression be no more than 1/2,
And air bag decrement is close to 2/3)；
2. the compressed air sealed in air bag 3 assigns air bag 3 with adjustable rigidity；
3. the structure of air bag 3 is simple, compact, be conducive to reduce utility model overall volume.
4. air bag 3 and the contact area of cylinder body 1 are big, be conducive to be pressurized heating air heat dissipation, thus accelerate energy dissipating into
Journey improves damping effect.
As shown in Fig. 2, being equipped with 4 cavitys 11 being parallel to each other in cylinder body 1.1 middle part 1 two sides cavity 11a of cylinder body and cylinder body
The position of air bag 3 in cavity 11b is opposite.Mode associated with cavity is conducive to enhance the horizontal rigidity and energy dissipating of the utility model
(damping) damping effect.
Illustrate that specific embodiment of the present invention is as follows in conjunction with the embodiments:
As shown in Fig. 2, the connector in central cavity 11b at the corresponding piston rod of piston is fixed on the end A；By two sides sky
Connector in chamber 11a at the corresponding piston rod of piston is fixed on the end B.
When the end A quickly pushes piston compression to be located at central cavity to the piston rod (active) for when B end motion, being fixed on the end A
Air bag in 11b.After when the end A, piston rod moves horizontally distance and reaches critical point, the air bag in central cavity 11b pushes and its phase
End cap connecing, being close with the end B, moves horizontally cylinder body 1 towards the end B.Since the end B piston rod is fixed, the movement of cylinder body 1 is led
It is caused passively to compress to the air bag in the cavity 11a of two sides.The above-mentioned air bag being pressurized pushes connect with it the and end A again
The end cap being close, so that accepting 1 both ends horizontal of cylinder body reaches balance.
Compressed air is further compressed in air bag, and while gas volume reduces, gas temperature is increased.
By The Ideal-Gas Equation:
Wherein, p indicates perfect gas pressure,
V indicates perfect gas volume,
N indicates the amount of gaseous matter,
R is ideal gas constant,
T indicates perfect gas thermodynamic temperature.
Since the amount of compressed air in air bag will not change, thus air bag, after being compressed, gas pressure intensity certainly will increase,
The piston and piston rod and end cap to connect hence for it generates biggish reaction force, forms the restoring force of horizontal direction.
Moving distance and movement speed of the end A to the end B can be controlled using above-mentioned restoring force, and can be acted at the end A
After power disappears, piston rod is pushed to set back by the original pressure of compressed gas closed in air bag.
While piston rod compresses air bag, cylinder body 1 radiates to air bag and cavity inner wall.Pass through heat
It dissipates to cut down the kinetic energy of piston rod generation, carries out damping using the principle of damping energy dissipation.
