Self-sensing magnetorheological damper adopting spiral damping channel

Abstract

The invention discloses a self-sensing magnetorheological damper adopting a spiral damping channel. The self-sensing magnetorheological damper comprises a working cylinder and a piston, wherein the piston is arranged inside the working cylinder and divides the working cylinder into a cavity I and a cavity II; the cavity I and the cavity II are filled with a magnetorheological material; an excitation coil and the spiral damping channel, which is used for enabling the magnetorheological material to flow in the cavity I and the cavity II, are arranged on the piston; the magnetic field of the excitation coil penetrates the spiral damping channel. According to the magnetorheological damper provided by the invention, the damping channel is a spiral damping channel, so that the effective length of the damping channel is lengthened, the magnetic field utilization ratio is increased, and the power consumption of the magnetorheological damper during adjustment is reduced.

Description

technical field [0001] The invention relates to the technical field of vibration buffering, in particular to a self-sensing magneto-rheological damper adopting a spiral damping channel. Background technique [0002] The magnetorheological damper is an intelligent shock absorbing device developed with the magnetorheological fluid as the filling material, which can change in milliseconds under the action of the magnetic field under the action of the magnetorheological fluid. Used in vehicles, aerospace, heavy machinery and weapons and other fields. In practical applications, the damping force output by the magnetorheological damper can be adjusted steplessly by the controller according to the demand, but the adjustment process consumes electric energy, so how to extend the effective length of the damping channel to improve the utilization of the magnetic field, and then Reducing the power consumption of the magneto-rheological damper during the adjustment process has been a g...
