Abstract

Forced vibration of viscoelastically damped three-layer sandwiched beams is considered. The sandwiched beam is assumed to be fixed at one end and is excited by a harmonic force at the other end. The displacement response of the beam is computed and an approximate transfer function including three consecutive modes is extracted. Vibration of damped sandwich beam is actively controlled by employing a PPD feedback controller. Comparison of the results verified the effectiveness of the proposed method.
