Abstract

The invention discloses a magneto-rheological damper with a multi-magnetic coupler structure, which comprises a piston, a piston rod and a magnetically conductive cylinder; the piston is arranged inside the magnetically conductive cylinder, and a magnetic Rheological fluid; the piston rod is set inside the piston, and the piston rod is used to drive the piston to rotate or move axially or simultaneously; when the piston rod drives the piston to rotate, the magnetically conductive cylinder and the magnetorheological fluid generate shear Cut damping hinders the rotation of the piston; when the piston rod drives the piston to move axially, the magnetically conductive cylinder and magnetorheological fluid produce valve-type damping to hinder the axial movement of the piston; when the piston rod drives the piston to rotate and move axially at the same time, The magnetically conductive cylinder and magnetorheological fluid simultaneously produce shear damping and valve damping to hinder the rotation and axial movement of the piston. The magneto-rheological damper provided by the invention can simultaneously provide shear damping and valve damping.

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...
