Abstract

The invention discloses a double-rod magnetorheological elastomer damper, which comprises two damping rods, a damping block, four damping rollers and a working cylinder. The cross section of an inner cavity of the working cylinder is rectangular, baffle plates are fixed to two ends of the working cylinder, a hole is arranged in the middle of each baffle plate, a sliding bearing is fixed into each hole, and a magnetorheological elastomer is fixed to the surface of each of two short inner edges of the working cylinder. The longitudinal section of the damping block is I-shaped, an excitation coil is wound in the middle of the damping block, the end faces of four branches of the I-shaped damping block are respectively provided with a semicircular groove, the axis line of each groove is perpendicular to that of each damping rod, and the diameter of each groove is larger than that of each damping roller. The damping rollers are mounted in the semicircular grooves on the end faces of the four branches of the I-shaped damping block, one end of one damping rod and one end of the other damping rod are fixed to two ends of the damping block respectively, the other ends of the two damping rods extend out of the working cylinder respectively through the sliding bearings on the baffle plates at the two ends of the working cylinder.

Description

technical field [0001] The invention belongs to a damper, in particular to a magnetorheological elastic body damper with double outlet rods. Background technique [0002] The existing double-rod magneto-rheological damper mainly adopts the structure of working cylinder, piston and piston rod, and at the same time, the working cylinder is also filled with magnetorheological fluid, such as the Chinese patent application number: 03132633.1 "built-in airbag type Double-rod magnetorheological fluid damper", this type of magnetorheological damper generates damping force through the reciprocating motion of the piston in the working cylinder driven by the piston rod. In order to prevent the magnetorheological fluid in the working cylinder from Taken out of the working cylinder, usually a sealing device is used between the working cylinder and the piston rod to solve the dynamic sealing problem of the piston rod. Since the magnetorheological fluid is a mixture of fine powders contain...
