Method and apparatus for circulating magnetic rheid non-linearly in magnetic gap space

Abstract

The invention relates to a process and apparatus for realizing non-rectilinear ring current in magnetic gap space for magnetic deformation fluid, wherein the magnetic gap space comprising a magnetic conductor and a magnetic insulator is provided with a magnetic insulation press ring, which insulates the magnetic gap space into the flow passage of the magnetic deformation non-rectilinear ring flow, the magnetic deformation flow enters the magnetic gap space from the entry port of the magnetic gap space, then extends along the ring flow defined by the magnetic gap space to the exit for outflow.

Description

technical field [0001] The invention relates to a fluid throttling device, a fluid damper, and a magnetorheological fluid damper of a hydraulic system, especially a magnetorheological fluid damper in a magnetorheological fluid shock absorber / shock absorber; A method and device for non-linear circulation of fluid in a magnetic gap space. Background technique [0002] Compared with the circulation of traditional fluids, the circulation of magnetorheological fluids has its own limited conditions. One is that the flow direction of the magnetorheological fluid must be perpendicular to the direction of the magnetic field; secondly, the circulation of the magnetorheological fluid occurs in a very limited space, which is the magnetic gap space; , response time and a given magnetorheological fluid, the high pressure difference can be obtained in the following ways: one is to place the magnetorheological fluid at the maximum magnetic field strength and not greater than the magnetic f...

In actual design, due to the limited magnetic gap space, it is very difficult to realize the above two approaches at the same time

[0003] A magneto-rheological fluid damping device such as US6471018B1 "Magneto-Rheological Fluid Device" (magneto-rheological fluid device) discloses a "Z"-shaped structure, and the "Z"-shaped structure is arranged in the inner cavity of the electromagnetic solenoid In the magnetic field, the circulation in a limited section and on different levels is realized, but the "Z" shape structure is processed on the same magnetic conductor of the piston head, although the flow direction is perpendicular to the direction of the magnetic field line, it is not enough The advantage is that the magnetic field strength in the flow channel processed on the same magnetic conductor is very weak, because most of the magnetic force lines are bypassed by the magnetic conductor, and the formed flow channel is theoretically not in the magnetic gap with dense magnetic force lines, so the magnetorheological effect i
