Paper Abstract

A power-generated magnetorheological (MR) damper with integrating a controllable damping mechanism and a power-generation mechanism is proposed in this paper. The controllable damping mechanism is realized by an annular rotary gap filled with MR fluids working in pure shear mode. The rotary damping moment is transformed to a linear damping force via a ball-screw mechanism. The power-generation mechanism is realized via a permanent magnet rotor and a stator with winding coils, which transforms the vibration energy of the system into electric power or directly to power the controllable damping mechanism. The characteristics of the controllable damping force and the power-generated performance are theoretically analyzed and experimentally tested.
