Parallel magneto-rheological shock absorber

Abstract

The invention discloses a parallel magneto-rheological shock absorber. The parallel magneto-rheological shock absorber comprises a magneto-rheological elastic body, a buffering part mounting plate, a magneto-rheological liquid tank, a piston block and an annular coil, wherein a bottom barrel is connected with one end of a middle barrel; the other end of the middle barrel is connected with a top barrel; a fixed separation plate is further mounted between the bottom barrel and one end of the middle barrel; a fixed separation plate is further mounted between the other end of the middle barrel and the top barrel; a fixed outer barrel is mounted at the other side of a main body; the coil is fixed in a coil mounting hole through a coil fixing ring and the fixed outer barrel is mounted on the mounting plate; a piston rod stretches out of the outer side of the fixed outer barrel; the magneto-rheological liquid tank is mounted at the lower end of the mounting plate; the piston block is mounted in a magneto-rheological liquid cavity; the piston block is internally provided with a flow channel; an upper cavity, a lower cavity and the flow channel are fully filled with magneto-rheological liquid; the annular coil is mounted at the outer side of the magneto-rheological liquid tank; the other end of the piston rod is connected with the piston block. The parallel magneto-rheological shock absorber is simple in structure, easy to manufacture and convenient to mount, has a good shock absorption effect and can be widely popularized and applied.

[0002] Traditional vibration isolators generally use rubber to reduce vibration. Since the discovery of magnetorheological fluid materials, the vibration absorber has reached a new level, and the effect of vibration reduction is much better than traditional traditional vibration absorbers. Magnetic The development of rheological fluids has gone through electrorheological fluids to magnetorheological fluids, and then developed from magnetorheological fluids to magnetorheological elastomers. Magnetorheological fluids and magnetorheological elastomers are two kinds of smart materials, each with its own characteristics. , the magnetorheological fluid usually works in the state after yielding, and the damping is changed. The magnetorheological elastomer can only work in the state before yielding, and the stiffness is adjusted. Therefore, if the coupling effect of the two is considered, some actuators are required to have a compact structure. Fields with a wide frequency response range, such as vibration control of precision instruments, have broad application prospects; at present, there are also patents that combine the two, such as Chinese patent: 200710092716.9, which uses magnetorheological fluid and magnetorheological elastomer, which has a certain reduction vibration effect, but the structural layout is very unreasonable, and the coil installation fluid is very inconvenient; for this reason, it is necessary to design a better parallel magneto-rheological shock absorber
