압전재료와 점탄성재료를 이용한 평판진동 음장의 능동제어

초록

This paper presents an active vibration and sound control of a plate using piezoelectri materilas and viscoelastic materials. Modeling and control strategies are undertaken. Active control of sound fields has been carried out using 3 pairs of piezoelectric sensor/actuator and a pair of viscoelestic material by passive constrained layer damping treatment.
