Abstract
A methodology to synthesize a predesignated acoustic response using a structure driven by multiple induced-strain actuators, e.g., piezoelectric (PZT) patches, is presented. The proposed approach of solving the inverse problem of structural acoustics, e.g., how to produce a known acoustic response from a given PZT-driven baffled plate, is accomplished using the impedance method. A dynamic model that assembles the PZT patch impedance, the host structure impedance, and the acoustic impedance is developed and then is utilized to synthesize a predesignated acoustic response. The proposed model includes the mass and stiffness of the actuator and thus provides a more accurate prediction when a structure is bonded with multiple actuators.
