Shape Control of Vibrating Simply Supported Rectangular Plates

摘要

We determine the optimum location of a given rectangular piezoceramic(PZT) actuator that will require the minimum voltage to annul the deflections of a simply supported rectangular linear elastic plate vibrating near one of its fundamental frequencies. Keeping the location of the centroid and the shape of the PZT fixed, we ascertain the voltage required as a function of the length of its diagonal to nullify the deflections of the plate.
