Multiple-piece two-dimensional magneto-rheological damper

Abstract

The invention discloses a multiple-piece two-dimensional magneto-rheological damper comprising a shell, a core part and a magnetic field generator, wherein the shell is internally provided with a circular ring and is provided with equal-diameter through holes on an upper bottom surface and a lower bottom surface; the core part is provided with at least two disks axially perpendicular to a mandrelon the mandrel and is arranged on the shell and in the central through holes of the upper bottom surface and the lower bottom surface of the shell; the disks arranged on the mandrel are parallelly crossed with the circular ring inside the shell or the upper bottom surface and the lower bottom surface of the shell; gaps are remained between the inner circumferential surface of the shell and the outer circumferential surface of the mandrel and between the circular ring inside the shell and the upper surface and the lower surface of the disks arranged on the mandrel; magneto-rheological fluid ormagneto-rheological grease is filled in the gaps; the shell is provided with the annular magnetic field generator; and the core part inside the shell can take any motion along the radial direction inside the shell. The invention regulates the size of magnetic field strength output by the annular magnetic field generator, thereby enabling the viscosity of the magneto-rheological fluid or the magneto-rheological grease inside the gap positioned between the shell and the core part to be changed, enabling the damping force received by the core part when the core part moves in the shell to be changed and enabling the damping force of the multiple-piece two-dimensional magneto-rheological damper to be controlled.

Description

technical field [0001] The invention belongs to a magnetorheological damper, in particular to a multi-piece two-dimensional magnetorheological damper. Background technique [0002] The existing published magneto-rheological dampers are mainly divided into two categories: one is the direct-acting type, and the other is the rotary type. These two types of magneto-rheological dampers have their clear scope of application. The rheological damper is suitable for vibration reduction occasions of various rotary motions, while the direct-acting magneto-rheological damper is suitable for vibration reduction occasions of reciprocating motion. Independently suitable for vibration reduction occasions of two-dimensional plane motion. Contents of the invention [0003] The purpose of the present invention is to propose a multi-piece two-dimensional magneto-rheological damper, which solves the situation where the existing magnetorheological damper cannot be independently applied to two-...
