Abstract

The invention provides a self-powered electrorheological elastomer damper which comprises an insulating shell, a pressing rod, an upper pressing plate, piezoelectric ceramic, a lower pressing plate, multiple electrode plates and electrorheological elastomers. A through hole is formed in the top of the insulating shell, the pressing rod penetrates the through hole, the upper pressing plate, the lower pressing plate, the electrode plates and the electrorheological elastomers are mounted in an inner cavity of the insulating shell, insulating paper is arranged between the pressing rod and the upper pressing plate, the piezoelectric ceramic is disposed between the upper pressing plate and the lower pressing plate, the electrode plates are disposed in the inner cavity of the insulating shell, insulating paper is arranged between the lower pressing plate and the electrode plates, one electrorheological elastomer is arranged between each two adjacent electrode plates, the upper pressing plate and the lower pressing plate are connected with the electrode plates through leads respectively, and the two electrode plates corresponding to a same electrorheological elastomer are connected with the upper pressing plate and the lower pressing plate respectively. The piezoelectric ceramic which is cylindrical is adopted for power generation, so that a strong electric field can be provided for the electrorheological elastomers, and self powering of the damper is realized; the self-powered electrorheological elastomer damper can adapt to vibrating environment better to realize vibration inhibiting.

Description

technical field [0001] The invention relates to a shock absorber, in particular to a self-powered electrorheological elastic body 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 electrorheological / magneto-rheological shock absorbers with variable damping recently studied have quick response and strong controllable damping force, but the disadvantage is that the electrorheological / magneto-rheological fluid currently configured is easy to settle, and the sealing The performance requirements are h...
