Non-Linear Phenomena of Piezo-Electric Ceramic Vibrator and Loci to Resonance Point of Non-Linear Region

Abstract

This paper proposes an electric resonance model of non-linear phenomena of the piezo-electric vibrator and determines all the loci which reach to the resonance point of the non-linear region. The mechanism of the phenomena is described by using the proposed model which assumes two types of resonance curves in the linear and the non-linear regions. The generation of the jumping phenomena clarified the dependence on three kinds of excitation methods used in the experiment. And all loci which reach the resonance point in a non-linear region are determined by the analysis of mechanical non-linear vibration and the experiment verification.
