Intelligent Magnetorheological Elastomer Shock Absorber

Abstract

The invention provides an intelligent magnetorheological elastomer shock absorber. The intelligent magnetorheological elastomer shock absorber comprises an insulated housing, a shock absorption rod, an upper conductive pressing plate, a lower conductive pressing plate, piezoelectric ceramic, a magnetic conduction support, a coil, an upper permanent magnet, a lower permanent magnet and a magnetorheological elastomer; the top of the insulated housing is provided with a through hole, and the shock absorption rod penetrates through the through hole; the upper conductive pressing plate, the lower conductive pressing plate, the piezoelectric ceramic and the magnetic conduction support are arranged in the insulated housing; the piezoelectric ceramic is arranged between the upper conductive pressing plate and the lower conductive pressing plate; the coil is arranged in an annular groove in the outer wall of the magnetic conduction support; both ends of the coil are respectively connected with the upper conductive pressing plate and the lower conductive pressing plate; the upper permanent magnet, the lower permanent magnet and the magnetorheological elastomer are arranged in an inner hole of the magnetic conduction support; the magnetorheological elastomer is positioned between the upper permanent body and the lower permanent body. The intelligent magnetorheological elastomer shock absorber provides an adjustable magnetic field for the magnetorheological elastomer in a manner of combining the permanent magnet with a magnetic field generated during power generation of the piezoelectric ceramic, is simple in structure and has better adaptivity.

Description

technical field [0001] The invention relates to a shock absorber, in particular to an intelligent magnetorheological elastomer shock absorber. Background technique [0002] At present, in terms of mechanical vibration reduction, the most common ones are still traditional hydraulic and pneumatic shock absorbers. Although the effect of this type of shock absorber is good, the disadvantage is that the damping is uncontrollable, the sealing performance is extremely high, and the processing accuracy of parts The requirements are harsh; and the hydraulic oil leaked from the hydraulic shock absorber is easy to pollute the environment. [0003] A series of electro / magneto-rheological shock absorbers with variable damping that have been studied recently have rapid response and strong controllable damping force, but the disadvantage is that the electro / magneto-rheological fluid currently configured is easy to settle, and the sealing performance requires High, and generally need to ad...

Problems solved by technology

However, the disadvantage of this shock absorber is that the sealing performance is high, the magnetorheological fluid is easy to leak and settle, and it needs an external power supply and control system, etc.
