Experiment on Vibration control of Beam using Active Constrained Layer Damping Treatment

능동구속감쇠 기법을 이용한 보의 진동제어 실험

The flexural vibration of aluminum beams with active and passive constrained-layer damping has been investigated experimentally to design structure with maximum possible damping capacity. Piezoelectric film is used as sensor and piezoceramic as actuator for negative velocity feedback control. This paper shows the effectiveness of active constrained-layer damping treatment through experiment, and we have carried out an experiment to study effect of beam thickness.
