Abstract

The invention discloses a magneto-rheological damper with a multi-magnetic couple stator structure. The magnetorheological damper includes: a piston, a support frame, a metal soft magnetic material, a magnetically conductive cylinder and an excitation coil; the support frame is a hollow structure; the piston is arranged inside the support frame; Magnetic materials; metal soft magnetic materials are overlapped and stacked layer by layer; the excitation coil is wound on the metal soft magnetic material; the metal soft magnetic material is set inside the magnetic conduction cylinder; there is a gap between the metal soft magnetic material and the magnetic conduction cylinder The gap is the rheological area of ​​the magnetorheological fluid; under the excitation of the excitation coil, the magnetic field lines start from the metal soft magnetic material, pass through the magnetorheological fluid rheological area, the magnetic conduction cylinder, and finally return to the metal soft magnetic material Inside, a multi-magnetic couple structure with simultaneous sending and receiving of magnetic lines of force is formed. The magneto-rheological damper provided by the invention can effectively suppress the eddy current heat generated by the changing excitation current, and improve the stability of damping force output.

Description

technical field [0001] The invention relates to the field of structural vibration control of bridges, vehicles, mechanical equipment, etc., in particular to a magneto-rheological damper with a multi-magnetic couple stator structure. Background technique [0002] At present, magnetorheological dampers have been widely used in many vibration reduction fields. With the continuous expansion of application fields, the requirements for miniaturization, light weight and large output damping force of magnetorheological dampers are gradually increasing; especially In some special application scenarios, due to the limitation of the shape design or space occupation of the damping object, it is required to meet the miniaturization, light weight and high damping force of the magneto-rheological damper, and at the same time, it is necessary to improve the structure of the damper. Be innovative to adapt to more applications. [0003] In the case that the magnetorheological damper requires...
