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-annular-membrane damper which comprises a work cylinder, a damping rod, large annular damping membranes, small annular damping membranes, an annular damping washer and two single-face annular electromagnets. The work cylinder comprises a drum and the two single-face annular electromagnets, the two single-face annular electromagnets are fixed to the two ends of the drum, and opposite poles of the two single-face annular electromagnets are opposite in direction. The large annular damping membranes and the small annular damping membranes are respectively composed of a magneto-rheological elastomer, the inner circumferences of the small annular damping membranes are fixed to outer circumferences of the tops of inner circular tubes, the inner circular tubes are fixed into center holes of the single-face annular electromagnets, the outer circumferences of the small annular damping membranes are fixed to the inner circumference of the annular damping washer, the outer circumference of the annular damping washer is fixed to the inner circumferences of the large annular damping membranes, and the outer circumferences of the large annular damping membranes are fixed to the inner circumference of a work cylinder circular tube. One end of the damping rod is fixed to the annular damping washer through a support, and the other end of the damping rod extends out of one end of the work cylinder through sliding bearings in the circular tubes, at one end of the work cylinder, of the single-face annular electromagnets.

Description

technical field [0001] The invention belongs to a magneto-rheological damper, in particular to a magneto-rheological elastic body double-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 be suitable fo...
