چکیده
Magnetorheological (MR) dampers, used as intelligent semi-active vibration control devices to achieve low energy consumption, fast response, controllability, and other capabilities are generally installed with a variety of sensors on their exterior ensure that the damping force can be accurately controlled. However, external often affected by complications reduce reliability damper, cost powering damper coils in remote locations where power is not available significantly increased. Based these problems, new self-powered MR scheme proposed. The proposed has both energy-harvesting greatly improves stability application range device converting into electrical supply excitation coil. drive piston rod linear reciprocating motion excitation, which converts mechanical via DC brushless three-phase generator after conversion double-linkage mechanism. At same time, generated passed coil change output damper. Meanwhile, performance efficiency experimentally tested. Experimental results show reaches 1040 N when applied current 0.6 A. an instantaneous voltage amplitude 1.782 V peak phase 4.428 W input 12.5 mm frequency 3 Hz.

Development of a Self-Powered Magnetorheological Damper System for Cable Vibration Control
A new self-powered magnetorheological (MR) damper control system was developed to mitigate cable vibration. The power source of the MR damper is directly harvested from vibration energy through a rotary permanent magnet direct current (DC) generator. The generator itself can also serve as an electromagnetic damper. The proposed smart passive system also incorporates a roller chain and sprocket,...
