DYNAMIC FORMULATIONS OF PLATES WITH SHUNTED PIEZOELECTRIC MATERIALS

摘要

Vibration control of plates with a passive electrical damper is presented in this paper. This electrical absorber, piezoelectric patches connected with a resistor and an inductor in series, is analogous to the damped mechanical vibration absorber. For estimating the effectiveness of piezoelectric absorber, the governing equations of motion are derived by applying a classical laminate plate theory and Hamilton's principle. The developed theoretical analyses are validated experimentally for the simply-supported aluminum plates in order to demonstrate the performance of a passive electrical damper. The developed models present invaluable means for designing and predicting the performance of the smart plates that can be used in many critical engineering applications.
