Device, fills any one in air, gas-pressurized or vacuum, bellows container top and the end in compressibility gum elastic cell cube
Two ends, portion welding circular patches, makes bellows container fully seal；Described hybrid isolator rigidity is divided into linearity range and non-linear
Section, during beginning, rigidity is provided jointly by bellows container and compressible rubber cell cube, after reaching critical point, hybrid vibration isolation
The rigidity of device is all provided by multilayer corrugated tubular container, and described critical point is the elastic restoring force of compressible rubber cell cube self
Balance with its internal gas pressure, therefore the rigidity of hybrid isolator is determined jointly by bellows container and compressible rubber cell cube
Fixed, the position of critical point is relevant with the character of compressible rubber cell cube.
In the present invention, fill air, gas-pressurized or vacuum in compressibility gum elastic cell cube, thus realize it can
The performance of compression, and hydraulic oil is the most compressible.
In the present invention, the quantity of compressible elastomeric rubber unit body can adjust, thus changes the rigidity of vibration isolator, adjusts
The vibration isolating effect of vibration isolator, improves its performance.
The invention has the beneficial effects as follows, invention introduces anti-fall multi-layer metal bellows structure of collapsing, and multilayer corrugated pipe
Container top and bottom ends welding circular patches seals, and can avoid the problem that conventional hydraulic oil cylinder oil plant is revealed, alloy material
Use make the present invention have oil resistivity, corrosion resistance, thermostability and be difficult to the advantages such as aging.Compressibility gum elastic unit
Internal fill air, gas-pressurized or for vacuum, thus realize its compressible performance, and hydraulic oil is the most compressible.
The quantity of compressible elastomeric rubber unit body of the present invention can adjust, thus changes the rigidity of vibration isolator, adjust vibration isolator every
Shake effect, improve its performance, finally make the collapse resistant capacity of structure effectively improve.

Fig. 2 is schematic top plan view.
Label in figure: 1. bellows container, 2. hydraulic oil, 3. compressible elastomeric rubber unit, 4. circular patches.
Detailed description of the invention
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
Embodiment 1:
The anti-fall multi-layer metal bellows solid-liquid hybrid isolator that collapses of the present invention, including bellows container 1, hydraulic oil 2, compressible
Gum elastic unit 3 and circular patches 4.
As shown in Figure 1, 2, bellows container 1 is built with consolidating of being made up of hydraulic oil 2 and compressibility gum elastic unit 3
Liquid blending agent, wherein can fill air, gas-pressurized or for vacuum, corrugated tube holds in compressibility gum elastic unit 3 body
Device top and bottom ends welding circular patches seals.Vibration isolation can be adjusted by the quantity changing compressible elastomeric rubber unit body
Device rigidity, thus play adjustment anti-vibration performance, improve the effect of vibration isolating effect, the employing of multilayer corrugated pipe, it is to avoid oil plant is let out
The problem of dew, the alloy material of corrugated tube has oil resistivity, corrosion resistance, thermostability and is difficult to the multiple advantages such as aging.
The influence factor of the effectiveness in vibration suppression of the multi-layer metal bellows solid-liquid hybrid isolator that collapses is resisted by theory analysis
Study.This individual system has two kinds of different states: the first state, the equation of motion of system is linear；The second shape
State, the athletic meeting of system presents obvious rough non-linear.
During the first state, system is in static balancing state, by concentrating directed force F, normal atmospheric pressure Pa, internal
Oil pressure p0, therefore system equilibrium equation is
