Abstract
The performance of shunt piezo damping is demonstrated by adding damping to the first mode of a plate with the dimensions of 28 by 38 cm and thickness of 0.8 mm. A small 1 by 2 inch piezoelectric patch with the thickness of 10 mil is bonded to the plate at a location where strain due to the first mode of vibration is high. The peizo is shunted with a resistance-inductance (RL) circuit, tuned to the first resonance frequency of the plate at 38 Hz. The plate is excited at its first natural frequency and the power spectrums of the acceleration at the center of the plate with and without the damping treatment were measured. These measurements showed that the shunt piezo damping treatment tuned to the first mode added an appreciable amount of damping to that mode.
