The vibration isolators on the basis of the material “metal rubber”

The vibration isolators on the basis of the material “metal rubber”.

 

 

Vibration-based material “metal rubber” significantly superior in terms of reliability and resource of traditional damping materials. Material “metal rubber” has the useful properties of rubber and is able, however, to withstand aggressive environments, high (up to 400 ° C) and low temperatures and other adverse external influences.

Benefits and properties

 


Description:

In modern technology are widespread objects exposed to vibration and impact, or generating vibration or mechanical shock. To reduce vibration and shock loads on the appliances or base vibration isolators are widely used. In some cases, they work under extreme conditions of high and low temperatures, vacuum, radiation, aggressive media – acids, oils, fuel, and needs to sustain long-term (tens of years) time. The vibration isolators on the basis of elastomers, these requirements are not able to perform, and spring have too little damping. For effective vibration protection in such conditions only apply all-metal vibration isolation devices based on dry friction, which include isolators from damping wire material, the so-called material “metal rubber”.

Metal rubber is a porous metal structure obtained by cold pressing of the workpiece from the wire to final shape and dimensions of the part. As experience has shown, a method of obtaining material “metal rubber” allows flexible management of the properties due to the choice of the wire material, its diameter, the method of installation in a mold, compacting pressure, the method of forming of the workpiece.

Metal rubber is already used in the space industry.

 


Benefits and properties:

– vibration-based material “metal rubber” significantly superior in terms of reliability and resource of traditional materials

material “metal rubber” has the useful properties of rubber and is able, however, to withstand aggressive environments, high (up to 400 ° C) and low temperatures and other adverse external influences. This is due to the special technology of weaving and pressing a coiled metallic filaments of different diameters,

since the processes of destruction of the products made from this material develop relatively slowly, and because metal tires can easily withstand temperatures up to 400 OC, and also has a high resource indicators

the destruction of extruded filaments of a spiral within the vibration absorber its damping properties are enhanced.
