Paper Abstract

The electromechanical surface damping (EMSD) technique, for controlling the peak vibration amplitudes of beam-like structures, is modified to extend the effective range of the approach. The technique is a combination of the constrained layer damping and the shunted piezoelectric methods, where the viscoelastic constrained layer attached to the vibrating surface is constrained by a shunted piezoelectric ceramic element. The mathematical model of the modified EMSD element is presented, implemented into a finite element algorithm and applied to demonstrate the ability of the technique to simultaneously and effectively suppress the first three resonant peaks of a generic aluminum cantilever beam.
