Paper Abstract

Negative impedance shunts have been used with piezoelectric materials for the purposes of vibration suppression. Details of the shunt design may be determined using different performance objectives such as maximum dissipation or minimization of reactive input power. Experimentally optimized shunts are applied to a composite piezoelectric aluminum beam subjected to a broadband disturbance. Performance measures of interest include an overall power balance for the system, as well as tip vibration suppression and spatial average vibration suppression. The resulting measures are compared to the wave-tuning and reactive power input tuning suppression theories.
