摘要

The present work aims to simulate, using the finite element method (FEM), the piezo-shunting of a PZT-actuated vibrating plate, i.e. the connection to a collocated PZT sensor of a multiple-mode electric shunt system to mechanically damp the plate vibration. This (so called) adaptive plate should work independently of any exterior counter power. Through also bonding the plate to an air cavity, the simulation is then extended to some vibroacoustical aspects, such the frequency response of the piezoelectric-vibrational-acoustic system in both directions. Furthermore, piezoelectric and acoustic actuation modes are tested to possibly act the one against the other, this attempt offering a second alternative to the electric shunt in damping the plate vibration. The piezo-shunting effect in the damping of the plate vibration is smaller than the calculated one obtained in the case of a beam, because not all the eigenmodes of the plate can be actuated and/or damped.
