摘要：

Piezoelectric control of thermally induced vibrations of rectangular and circular plates exhibiting strain-rate damping is investigated. The plates consist of a thermoelastic structural layer bonded to two outer piezothermoelastic layers. Electric pulses are applied to the piezoelectric layers in order to suppress the vibration. The initiation and termination times of the pulse voltages are calculated according to a procedure similar to a method proposed earlier by the authors; amplitudes of the pulses are determined by various control strategies, including those based on speed feedback. Numerical results are presented for aluminum/PZT ceramic plates.
