Abstract

The invention discloses a rotary-type magneto-rheological damper. The rotary-type magneto-rheological damper comprises a cylinder tube, a rotatably-arranged rotor assembly, a rotating shaft outer ringarranged on the rotor assembly in a sleeving mode, a first excitation coil arranged on the rotating shaft outer ring, a second excitation coil arranged on the cylinder tube, and a damping channel forming device arranged between the rotating shaft outer ring and the cylinder tube. The damping channel forming device is provided with a first damping channel and a second damping channel which allow magneto-rheological liquid to pass, and the first damping channel and the second damping channel are arranged to be able to be switched between the connecting state and the disconnecting state. According to the rotary-type magneto-rheological damper, by changing the lengths of the damping channels, adjusting control over the magnitude of damping force is achieved, thus the damper has wider-range adjustable damping torque, and the adaptability of the damper is improved.

Description

technical field [0001] The invention belongs to the technical field of dampers, in particular, the invention relates to a rotary magnetorheological damper. Background technique [0002] Magneto-rheological fluid is a suspension formed by mixing tiny soft magnetic particles with high magnetic permeability and low magnetic hysteresis and non-magnetic liquid. Under the condition of zero magnetic field, the particle distribution of the magnetorheological fluid is chaotic, showing the characteristics of low-viscosity Newtonian fluid; under the action of a magnetic field, it is regularly arranged in chains or chain bundles, and can be instantly changed from Newtonian fluid to It is a plastic Bingham fluid with high viscosity and difficult flow. This change is reversible, and the magnitude of the damping force can be controlled by controlling the strength of the magnetic field. [0003] The magnetorheological damper that is more commonly used at present is a linear magnetorheolog...
