Reduction of Plate Vibration and Acoustic Radiation via Adaptively Controlled Boundaries
Abstract
Reduction of plate vibration and acoustic radiation at low frequencies via adaptively controlled boundaries is experimentally demonstrated. The control is based on changing the clamping pressure at the boundaries of the plate to continuously detune the plate resonance frequencies from the frequency of pure-tone excitation. Results are presented for the control plate vibration with single and varying frequencies of excitation and for the control of acoustic radiation with single frequency excitation....
