Summary:

The motivation of this research is to replace the conventional steel automotive roof by laminated composite plate for light weight and high damping. The coupled finite/boundary element method is used in numerical analysis for acoustic radiation from the vibration of rectangular composite plate which is simply supported. This analysis is validated using the Wallace equation for an isotropic plate. Active control of sound fields has been carried out using 3 pairs of piezoelectric sensor/actuator and a pair of viscoelastic material by passive constrained layer damping treatment. The results show that the optimal placement of piezoelectric sensor/actuator and VE patch is required to control the sound fields from vibrating composite plate. It is concluded that the conventional steel automotive roof could be replaced by the laminated composite
