Abstract

Self-supplied electromagnetic rheological damper and magneto-rheological damping system, wherein, the self-supplied electromagnetic rheological damper includes a cylinder body, a piston rod, a stator, a connecting rod and several permanent magnets, and the cylinder body has a cavity with a first opening and a second opening Cavity structure, the cavity is filled with magnetorheological fluid; the piston rod is connected to a piston with a piston coil located in the cavity, and its first end extends out of the first opening, and its second end extends out of the second opening; the stator includes There is a housing cavity with a retractable opening, and a number of protruding teeth of high magnetic permeability materials are arranged at intervals on the inner wall of the housing cavity. The top of each protruding tooth extends along the axial direction to form side teeth, and the adjacent protruding teeth and side teeth form a housing and a piston. The groove of the electromagnetic coil electrically connected to the coil; the connecting rod is located in the accommodating cavity, and has a first connecting end protruding from the retractable opening and connected with the second end of the piston rod; several permanent magnets are connected with the connecting rod, correspondingly Magnetic poles are arranged between adjacent permanent magnets. The invention can realize self-power supply, and has high electromagnetic utilization rate.

Description

technical field [0001] The invention relates to a semi-active magnetorheological vibration control technology, in particular to a self-supplied electromagnetic rheological damper. Background technique [0002] Magneto-rheological fluid is a smart material with unique functions. Its rheological properties can change rapidly and reversibly under the condition of magnetic field. Using the properties of magnetorheological fluid, a magnetorheological damper is produced. Magnetorheological dampers not only have the adjustability of active control system transmission, but also have the reliability of passive control. Therefore, they are gradually used in vibration control in aerospace, engineering construction, automotive engineering and other fields. In these fields, although the magnetorheological damper can greatly improve the ability of vibration control, the magnetorheological damper needs an external magnetic field to change the shear yield stress of the magnetorheological fl...
