Active Vibration Control of a Magnetorheological Sandwich Beam Lei Chen and Colin H Hansen School of Mechanical Engineering Adelaide University Adelaide SA5005 Australia ABSTRACT Sandwich beam structures constructed with MR fluids can be implemented as distributed vibration absorbers to suppress unwanted vibrations This paper introduces an analytical model for MR The applied magnetic field on the free end of the test panel was capable of reducing until 37 45% their first natural frequency value It can be noted from numerical and experimental results that sandwich panel with MRE honeycomb shifted the natural frequencies due to the increase of an induced magnetic field especially for the first mode shape
