Embodiment Construction

[0015] see figure 1 Shown: a magneto-rheological elastomer shock absorber, including a shock-absorbing rod 2 , an inner sleeve 1 , and a base 3 axially connected together. The damping rod 2 extends into the inner sleeve 1, and a piezoelectric module and a damping module are axially arranged between the damping rod 2 and the base 3 in the inner sleeve 1 (that is, the inner sleeve The inner surface of the bottom opening of 1 is threadedly connected with the outer circumference of the top of the base 3. Inside the inner sleeve 1 are the damping rod 2, the piezoelectric module and the damping module in sequence from top to bottom, and the damping rod 2 extends upwards out of the inner sleeve. 1 through hole on top). Wherein, the piezoelectric module is mainly composed of an upper conductive electrode plate 4, a nylon protective cover 15 and a lower conductive electrode plate 5 arranged axially together. Between the upper conductive electrode plate 4 and the lower conductive elect...

Abstract

The invention discloses a magnetorheological elastomer shock absorber which comprises a shock abosrbing rod, an inner sleeve and a base, wherein the shock absorbing rod, the inner sleeve and the base are connected together in the axial direction. The shock absorbing rod extends into the inner sleeve. A piezoelectric module and a shock absorption module are axially arranged between the portion, in the inner sleeve, of the shock absorbing rod and the base. The shock absorption module is mainly composed of an upper permanent magnet, an upper magnetorheological elastomer, a ferromagnet, a lower magnetorheological elastomer and a lower permanent magnet which are arranged together in the axial direction. A coil is arranged on the periphery of the ferromagnet. The two ends of the coil are connected with the piezoelectric module correspondingly. The magnetorheological elastomer shock absorber is compact in structure and high in shock absorption property.

Description

technical field [0001] The invention relates to a shock absorber, in particular to a magneto-rheological 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] Chinese patent literature discloses an "intelligent magnetorheological elastomer shock absorber" (patent number CN201510213495.0 Announcement date: 2015.08.12), the intelligent magnetorheological elastomer shock absorber includes an insulating shell and a shock absorber rod , an upper conductive voltage plate, a lower conductive voltage plate, piezoe...
