This paper describes piezoelectric switching techniques for vibration damping. The dynamical behaviour of a
piezoceramics connected to a switching LR shunt and the dissipated energy are obtained using a fundamental
piezoelectric model. All calculations are performed in a normalized way and highlight the influence of the
electromechanical coupling coefficient of the piezoceramics and the shunt parameters. For the first time, a precise result
for the dynamics of a shunted piezoceramics is derived. The analytic results are used to determine the optimal switching
sequence and external branch parameters in order to maximize the damping performance. The results are validated by
measurements of a clamped beam.
