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 elastic body annular-membrane-type damper. The magneto-rheological elastic body annular-membrane-type damper comprises a working cylinder, a damping rod, two annular damping membranes, two annular damping sheets, an annular iron plate and two single-face annular electromagnets, wherein the working cylinder is composed of a circular pipe and the two single-face annular electromagnets, at least four pairs of magnetic poles are evenly distributed on one circular ring face of each single-face annular electromagnet, and a magnet exciting coil is wound on each magnetic pole; the annular iron plate is fixed on the inner circumference of the circular pipe, between the two single-face annular electromagnets, inside the working cylinder, the two annular damping membranes are composed of magneto-rheological elastic bodies, the outer circumferences of the two annular damping sheets are fixed on the inner circumferences of the two annular damping membranes respectively, and the outer circumferences of the two annular damping membranes are fixed on the inner circumference, between the two single-face annular electromagnets and the annular iron plate, of the circular pipe respectively in parallel; one end of the damping rod penetrates through two middle holes of the two annular damping sheets and is fixed with the two middle holes of the two annular damping sheets, and the other end of the damping rod extends out of the working cylinder via a sliding bearing on one of the single-face annular electromagnets.

Description

Technical field [0001] The invention belongs to a magnetorheological damper, and in particular relates to a magnetorheological elastomer annular film type damper. Background technique [0002] Magnetorheological damper is an intelligent damping device. The existing magnetorheological damper mostly adopts the structure of piston and working cylinder. Most of the pistons are cylinders made of magnetically conductive metal. The viscosity of the magnetorheological fluid is used to adjust the output damping force. This type 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 It is suitable for the vibration reduction requirements of high frequency and small amplitude vibration occasions. Summary of the invention [0003] In view of the large mass of the piston in the existing magnetorheological damper and it is difficult to apply to high frequency and sm...
