The effects of pressure loading on the dynamics of a curved piezostructure

In an article previously published in this journal by the authors, a state- space model of a curved piezostructure was developed and used to investigat e the effects of curvature on panel dynamics. Panel curvature was shown to increase control system bandwidth and to affect transducer coupling. In the present work, the model is extended to include the effects of internal pre ssure loading on the dynamics of a curved piezostructure. The impact of int ernal pressure loading on the dynamics of a curved piezostructure, and subs equently on active structural acoustic control (ASAC) of sound transmission through it, are reviewed.
