This paper proposes an identification system of the important parameter (generalized electromechanical coupling coefficient) for passive vibration suppression system by piezoelectric element which has compact structure and simple procedure. The proposed system consists of piezoelectric element, external impedance, voltage source and bridge circuit. Voltage input causes the resonant oscillations of the system and the system yields some resonant frequencies which can be observed from the voltage… CONTINUE READING
