By changing the current, the rheological property of the magnetorheological fluid can be effectively controlled, and the magnetorheological damper with continuously adjustable damping force can be designed according to the principle.
At present, most of common magnetorheological dampers are telescopic valve type magnetorheological dampers, pressure difference is generated between an upper cavity and a lower cavity through the up-and-down movement of a piston, so that magnetorheological fluid flows through a damping channel on the piston, and controllable damping force is generated by applying the flow mode of the magnetorheological fluid. The magnetorheological damper can provide small damping force at low frequency. Considering that the roll frequency of a vehicle body is low when the vehicle runs in a steering mode, the telescopic valve type magnetorheological shock absorber cannot provide enough damping force to achieve effective roll control, and a rollover accident of the vehicle is caused in a serious situation.

When no external magnetic field is applied to the magnetorheological damper designed by the invention, the particles in the magnetorheological fluid are distributed disorderly, and at the moment, the telescopic cylinder can continue to move as long as overcoming the viscous resistance moment, so that the damping force provided by the telescopic cylinder is very limited. When an external magnetic field exists, particles in the magnetorheological fluid are distributed in a chain-beam shape along the direction of the magnetic field, the magnetorheological fluid develops from fluid to semi-solid, at the moment, the motion of the telescopic cylinder needs to overcome the shear stress between the telescopic cylinder and the magnetorheological fluid, the shock absorber works in a shear mode, and the shear stress is increased along with the increase of the magnetic field intensity.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Wherein: the inner cylinder, the outer cylinder and the telescopic cylinder 3 form a closed cavity, and magnetorheological fluid is filled in the cavity. The linear motion bearing 5 is fixed by an end cap 20, and the end cap 20 and the outer cylinder 7 are connected by a bolt B21. The telescopic cylinder 3 reciprocates vertically between the inner cylinder and the outer cylinder, the coil base 11 is connected with the telescopic rod 4, the coil base 11 is made of magnetic conductive electrician pure iron, 3 annular coil grooves are formed in the coil base, and enameled wires are wound in the coil grooves. Two sealing rings 6 are respectively arranged between the inner cylinder 8 and the telescopic cylinder 3 and between the outer cylinder 7 and the telescopic cylinder 3, so that magnetorheological fluid is prevented from flowing out of the cavity. The end cap 20 is secured to an annular boss on the upper part of the outer cylinder 7 by bolts B21. The bottom of the outer cylinder 4 is provided with a small hole, the compensation cylinder 17 is connected through the small hole, the compensation cylinder 17 is divided into an upper cavity and a lower cavity by the compensation piston 18, the lower cavity is connected with the outer cylinder 7, magnetorheological fluid is filled in the lower cavity, the top of the upper cavity is provided with an air nozzle 19, gas with certain pressure is injected into the upper cavity through the air nozzle 19, and a gasket 16 is arranged between the compensation cylinder 17 and the outer cylinder 7 and is connected together through a bolt A15.
The working principle of the shear mode magneto-rheological damper is as follows: the upper suspension ring 1 of the magneto-rheological shock absorber is connected with a vehicle body, and the lower suspension ring 14 is connected with a vehicle frame. When the vehicle runs, the magnetorheological damper makes stretching and compressing motion along with the relative motion of the upper connecting part and the lower connecting part, the telescopic cylinder 3 makes vertical reciprocating motion up and down to drive the coil base 11 fixed on the telescopic rod 4 to move back and forth, and a working gap 9 is reserved between the inner cylinder and the outer cylinder and the telescopic cylinder 3. Due to the existence of the compensation cylinder 17, the magnetorheological fluid can be ensured to be filled in the magnetorheological fluid chamber all the time. The shearing stress generated between the inner wall and the outer wall of the telescopic cylinder 3 and between the inner cylinder 8 and the outer cylinder 7 changes along with the magnetic field intensity, the magnetic field intensity is influenced by the current in the coil 12, and the continuous control of the damping force generated by the shock absorber can be realized by controlling the size of the electrified current in the coil 12. The magneto-rheological shock absorber designed by the invention mainly depends on the shear mode of the magneto-rheological fluid to generate damping force, the damping force model of the shear mode is related to the hydrodynamic viscosity and the yield strength of the magneto-rheological fluid, and the hydrodynamic viscosity can be ignored compared with the shear yield stress of the magneto-rheological shock absorber, so that the magnitude of the damping force has no great relation with the relative movement speed, when the speed is zero, a certain exciting current is applied, and a sufficient shear area is ensured, and a quite large damping force can be generated.
