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.
