Problems solved by technology

[0002] The magneto-rheological damper is an intelligent damping device. The existing magneto-rheological damper mostly adopts the structure of piston and working cylinder. The piston is mostly a cylindrical shape made of magnetically conductive metal. The viscosity of the magnetorheological fluid in the middle is used to adjust the output damping force. This kind of magnetorheological damper with a cylindrical piston structure is difficult to apply due to the large mass of the piston and the small gap between the piston and the working cylinder. Vibration reduction requirements for high-frequency and small-amplitude vibration occasions

Abstract

The invention discloses a magneto-rheological elastomer double outlet rod single ring film damper. The damper comprises a working cylinder, a damping rod, two annular damping films, two annular damping sheets and a double-sided annular electromagnet, wherein the working cylinder is cylindrical; end covers are fixed to the two ends of the working cylinder; the outer circumference of the two-sided annular electromagnet is fixed to the inner wall of the working cylinder between the two end covers; at least four pairs of magnetic poles are uniformly distributed on each annular surface of the two-sided annular electromagnet; an excitation coil is wound on each magnetic pole; the two annular damping films consist of magneto-rheological elastomers; the outer circumferences of the annular damping sheets are fixed to the inner circumferences of the annular damping films; the outer circumferences of the two annular damping films are fixed to the inner wall of the working cylinder between the two-sided annular electromagnet and the two end covers in parallel respectively; the damping rod penetrates through middle holes in the two annular damping sheets and the two annular damping sheets are fixed to the middle part of the damping rod; and the two ends of the damping rod extends out of the two ends of the working cylinder through sliding bearings on the two end covers of the working cylinder.

Description

technical field [0001] The invention belongs to a magneto-rheological damper, in particular to a magneto-rheological elastic body double-out rod single-ring film damper. Background technique [0002] The magneto-rheological damper is an intelligent damping device. The existing magneto-rheological damper mostly adopts the structure of piston and working cylinder. The piston is mostly a cylindrical shape made of magnetically conductive metal. The viscosity of the magnetorheological fluid in the middle is used to adjust the output damping force. This kind of magnetorheological damper with a cylindrical piston structure is difficult to apply due to the large mass of the piston and the small gap between the piston and the working cylinder. The vibration reduction requirements for high-frequency and small-amplitude vibration occasions. Contents of the invention [0003] Aiming at the problem that the mass of the piston in the existing magneto-rheological damper is too large to...
