Vibration Suppression of Flexible Beams Using MR Elastomers

Abstract:

Magnetorheological (MR) elastomers are smart materials whose physical properties can undergo instantaneous and reversible change when subjected to different intensities of the magnetic field. This makes the MR elastomers have wide applications in the fields of vibration control. This work presents the vibration suppression of flexible beams with MR elastomers. An experiment system has been set up to investigate the vibration performances of a sandwich beam filled with MR elastomers. The vibration response of the beam subjected to different magnetic field intensity and excitation frequencies are demonstrated and evaluated. The results obtained indicate that vibration attenuation is achieved at different operating conditions by applying a magnetic field to the beam.
