Permanent magnet type magneto-rheological elastomer vibration isolator

Abstract

The invention discloses a permanent magnet type magneto-rheological elastomer vibration isolator which comprises a magnetism isolating cylinder barrel, a magneto-rheological elastomer and a magnetic induction mechanism, wherein the upper and lower ends of the magnetism isolating cylinder barrel are connected with an upper cylinder cover and a lower cylinder seat separately; a first magnetic conduction rod is arranged in the magnetism isolating cylinder barrel at the upper end of the lower cylinder seat; the magneto-rheological elastomer is arranged on the first magnetic conduction rod; a second magnetic conduction rod is arranged at the upper end of the magneto-rheological elastomer and penetrates through the upper cylinder cover; the magnetic induction mechanism comprises a plurality of magnetic induction rings; the magnetic induction rings are connected between the upper cylinder cover and the lower cylinder seat in a sleeving manner; each of the magnetic induction rings comprises two permanent magnet blocks and two magnetism isolating blocks; and the two permanent magnet blocks and the two magnetism isolating blocks are alternately connected to form a circular ring shaped magnetic induction ring. The permanent magnet type magneto-rheological elastomer vibration isolator adjusts variation of the magneto-rheological elastomer through the novel magnetic induction mechanism to realize more efficient vibration isolation of the vibration isolator and is novel in structure, safe, reliable, and high in creativity and practicality.

Description

technical field [0001] The invention relates to a vibration isolator, in particular to a permanent magnet magneto-rheological elastomer vibration isolator. Background technique [0002] Mechanical vibration will affect the stability and service life of the structure and equipment. If the vibration amount deviates from the fixed position, the mechanical equipment will generate a lot of noise, and will reduce the service performance and life of the equipment. If the vibration is intensified, it will The premature fatigue failure of the mechanical equipment makes it impossible to operate normally, making the equipment invalid. With the development of science and technology, the modern mechanical structure is becoming more and more refined and complex, the situation of mechanical vibration is becoming more and more diverse, the speed of mechanical movement is increasing day by day, and the harm caused by mechanical vibration is becoming more and more obvious and intensified, so ...

AI Technical Summary

Problems solved by technology

[0003] The vibration isolators currently used include rubber vibration isolators and metal vibration isolators. This type of vibration isolator is a passive vibration isolator and has no energy input during operation. Each type of vibration isolator has a specific vibration isolation frequency. Only A good vibration isolation effect can only be produced at a specific frequency. If the external vibration frequency changes, the vibration isolation effect of the vibration isolator will be significantly reduced, and even the vibration isolation effect will not be achieved.
