The present invention has good anti-vibration performance, can the collapse resistant capacity of effective lift structure, by changing compressible bullet Property rubber unit body quantity can adjust vibration isolating effect, the employing of multilayer corrugated pipe simultaneously, it is to avoid the problem that oil plant is revealed, The alloy material of corrugated tube has oil resistivity, corrosion resistance, thermostability and is difficult to the multiple advantages such as aging.
Summary of the invention
The problems such as the fatigue life in order to overcome existing vibration isolator to exist is short, units age, fluid leakage, the mesh of the present invention Be a kind of multi-layer metal bellows formula solid-liquid hybrid isolator is provided, this device adds on the basis of traditional liquid-solid vibration isolator To improve, introducing alloy corrugated tubular construction, bellows container top and bottom ends welding circular patches seals and solves oil liquid leakage Problem.This vibration isolator has the advantage that traditional vibration isolator anti-vibration performance is good, solves tradition vibration isolator fatigue life simultaneously The problems such as short, rubber unit is aging, fluid leakage, and the collapse resistant capacity of lift structure.
The technical solution adopted for the present invention to solve the technical problems is: anti-fall collapse multi-layer metal bellows solid-liquid mixing every Shake device, and including bellows container, hydraulic oil, compressible elastomeric rubber unit and circular patches, bellows container is built with by liquid Force feed and the solid-liquid mixed media of compressibility gum elastic unit composition, described solid-liquid mixed media is full of whole corrugated tube to be held 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.

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
