Abstract

Different methods for suppressing random (turbulence induced) vibrations of a plate like wing with embedded piezoceramics are investigated. An electromechanically coupled finite element model (that accounts different external circuits) is combined with unsteady aerodynamic models (the doublet-lattice method and Roger’s model) to develop a piezoaeroelastic model of cantilevered plates representing wing-like structures. An atmospheric turbulence model (Von-Karman’s and Dryden’s spectrum) is used to induce random vibrations at different airflow speeds. An active controller and different piezoelectric shunt circuits – passive and hybrid (combining passive circuits and voltage sources – are applied to suppress random vibrations over a range of airflow speeds when a single pair of piezoceramics is modeled on the clamped end of the plate. The behavior of the piezoaeroelastic system is investigated in time and frequency domains. Simulation results demonstrate that the hybrid control approach is more effective than purely passive or active controllers.
