Magneto-rheological damper with multi-magnetic coupler substructure

Abstract

The invention discloses a magneto-rheological damper with a multi-magnetic coupler substructure. The magneto-rheological damper comprises a piston, a piston rod and a magnetic conductive cylinder barrel, the piston is arranged inside the magnetic conductive cylinder barrel, the space between the piston and the magnetic conductive cylinder barrel is filled with magneto-rheological fluid, the pistonrod is arranged in the piston, and the piston rod is used for driving the piston to rotate or axially move or simultaneously rotate and move axially. When the piston rod drives the piston to rotate,the magnetic conductive cylinder barrel and the magneto-rheological fluid produce shearing damp to hinder rotation of the piston. When the piston rod drives the piston to move axially, the magnetic conductive cylinder barrel and the magneto-rheological fluid produce valve type damp to hinder axial movement of the piston. When the piston rod drives the piston to simultaneously rotate and move axially, the magnetic conductive cylinder barrel and the magneto-rheological fluid simultaneously produce shearing damp and valve type damp to hinder the rotation and axial movement of the piston. By meansof the magneto-rheological damper, shearing damp and valve type damp can be simultaneously provided.

Description

technical field [0001] The invention relates to the field of structural vibration control, in particular to a magneto-rheological damper with a multi-magnetic coupler structure. Background technique [0002] Magnetorheological dampers have been widely used in many fields of vibration reduction. With the continuous expansion of application fields, the requirements for miniaturization, light weight and large output damping force of magnetorheological damper equipment are gradually increasing. While satisfying the miniaturization, light weight and high damping force of the magneto-rheological damper, it is necessary to innovate the structure to adapt to more applications. [0003] The magnetic circuit design in the magnetorheological damper is one of the important links in the construction of the damper, and its structure determines the working performance of the magnetorheological damper. Traditional magneto-rheological dampers often design the damping piston as an "I"-shaped...
