Magneto-rheological damper of multi-magnetic dipole stator structure

Abstract

The invention discloses a magneto-rheological damper of a multi-magnetic dipole stator structure. The magneto-rheological damper comprises a piston, a supporting frame, metal soft magnetic materials,magnet conductive cylinders and excitation coils; the supporting frame is of a hollow structure; the piston is arranged in the supporting frame; the multi-layer metal soft magnetic materials are embedded outside the supporting frame; the metal soft magnetic materials are arranged in a layers overlapped and stacked mode; the metal soft magnetic materials are wound with the excitation coils; the metal soft magnetic materials are arranged in the magnet conductive cylinders; gaps are arranged between the metal soft magnetic materials and the magnetic conductive cylinders; the gaps are magneto-rheological fluid rheological areas; and under the excitation of the excitation coils, magnetic force lines start from the metal soft magnetic materials, pass through the magneto-rheological fluid rheological areas and the magnetic conductive cylinders, and finally return to the metal soft magnetic materials to form the multi-magnetic dipole structure capable of transmitting and receiving the magneticforce lines at the same time. By adopting the magneto-rheological damper, the eddy current heat generated by the change excitation current can be effectively suppressed, and the stability of the damping force output is improved.

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...
