Paper Abstract

A study was undertaken to investigate low frequency vibration suppression of a large composite panel under acoustic excitation. Both passive and active techniques are examined. Passive damping is achieved with a peel and stick constrained layer damping treatment. The treatment uses a constraining layer with a stand-off spacer to increase damping performance. Active damping is achieved with surface bonded piezoceramic wafer actuators and a closed-loop controller. This paper will discuss the analytical modeling of both damping techniques and show comparisons with test data. The reduced vibration resulted in noise attenuation at panel resonance. This phenomenon will also be discussed with the presentation of accelerometer and microphone test data.
