Paper Title:
Vibration Control Using Shunted Electromagnetic Transducer
  Abstract

This paper describes vibration suppression of the flexible cantilever beams using shunted electromagnetic transducer. The proposed system consists of a coil attached on a cantilever and a permanent magnet placed under the bottom of the coil, and both ends of the coil were connected to the parallel resonant RLC shunt circuit. The dynamic model of cantilever beam with shunted electromagnetic damper was theoretically formulated and used to compare the analytic predictions with the experimental results. The vibration and damping characteristics of the flexible beams with the electromagnetic shunt damper were investigated by tuning the circuit parameters. Also, the effect of the magnetic intensity on the shunt damping was studied with the variation of the gap between the aluminum beam and the permanent magnet. Presented results show that the electromagnet shunt damper has good vibration reduction effect, and it can be successfully applied to reduce the vibration of the flexible structures.
