Description
Technical Field
The invention relates to the field of magnetorheological dampers, in particular to a bottom channel magnetorheological damper with a sedimentation active dispersing device.
Background
The magneto-rheological liquid is a suspension formed by mixing tiny soft magnetic particles with high magnetic conductivity and low magnetic hysteresis with non-magnetic permeability. Such suspensions exhibit newtonian fluid behavior of low viscosity under zero magnetic field conditions; under the action of strong magnetic field, the Bingham body has the characteristics of high viscosity and low fluidity. Under the condition of zero magnetic field, the magnetorheological fluid is a fluid with good fluidity, and the apparent viscosity is small; the apparent viscosity can be increased by more than two orders of magnitude in a short time (millisecond level) under the action of a strong magnetic field, and the solid-like characteristic is presented; and the change is continuous and reversible, i.e. returns to the original state after the magnetic field is removed. However, from the 50 s to the 80 s, magnetorheological fluids have been very slow to develop due to the lack of recognition of their potential ability to shear stress and the problems of suspension stability.
The magneto-rheological damper is a novel damper based on the modern bidirectional cylinder damper principle and using magneto-rheological fluid as a working medium. The magnetorheological damper can change damping force under the control of an external magnetic field, so valve system components such as a compression valve, a circulation valve, a recovery valve, a compensation valve and the like are not needed, the structure is simple, the reliability is good, and meanwhile, the magnetorheological fluid has the advantages of high yield stress, quick response and the like, so that the magnetorheological damper has bright prospect in engineering application.
However, magnetorheological dampers have to face the unavoidable problem of magnetorheological fluid sedimentation. The magnetorheological fluid consists of micron-sized soft magnetic particles and carrier fluid, wherein the density difference exists between the soft magnetic particles and the carrier fluid, the brownian motion of the micron-sized particles is weak, the gravity effect is strong, sedimentation in the carrier fluid is unavoidable, and the sedimentation problem of the magnetorheological fluid can be delayed to a certain extent by adding a surfactant and the like, but cannot be fundamentally overcome.
In order for magnetorheological dampers to function properly without being affected by sedimentation problems, researchers have made a difficult effort. Most of the research work has focused on alleviating the sedimentation problem of magnetorheological fluids, improving suspension stability, and has made great progress. However, even the magnetorheological fluid with the best suspension stability in the company LORD in the United states of America can generate macroscopic delamination and sedimentation after standing for about one month. Therefore, for a long time, it is desired to find a reasonable method, which can apply a certain external stirring effect to the magnetorheological damper in a static state, so as to promote the magnetorheological fluid which is settled to a certain extent to be redispersed, and keep the magnetorheological damper in a better state. Unfortunately, such structures have not been effectively implemented until now due to the complexity of the mechanical structure and practical problems of engineering application.
Accordingly, there is a need in the art for a device that overcomes the above-described problems.

The rotor 4 is positioned in the liquid cylinder 1, and the lower end of the rotor is supported in the round hole I2021 of the bottom cover 2 by the protruding shaft 401.
The stator 5 is made of silicon steel sheets in a superposition mode. The stator 5 includes an outer cylinder 501 and an inner cylinder 502.
The inner cylinder 502 is located inside the outer cylinder 501. A plurality of magnetic poles 503 are arranged between the inner cylinder 502 and the outer cylinder 501. Each pole 503 has a winding 504 wound thereon.
6 Through grooves II5021 penetrating through two ends of the inner cylinder 502 are uniformly distributed on the inner wall of the inner cylinder 502. On the inner wall of the inner cylinder 502 corresponding to the two adjacent magnetic poles 503, a through groove II5021 is provided, so that the winding 504 is conveniently wound.
