Abstract
This paper proposes the equivalent mechanical model and the equivalent electrical model for models of vibration suppression methods in flexible structures using piezoelectric elements. There are two main methods to suppress vibration of flexible structures. One is active vibration control and the other is passive vibration suppression. Because both of them include both mechanical and electrical system, the mechanism of the vibration suppression becomes complicated and can not be understood easily. To make matters worse, knowledge of the mechanical vibration suppression device and the electrical circuit are not utilized in those models using piezoelectric elements. Hence, this paper describes the way to derive the equivalent mechanical and electrical models and the effectiveness was investigated by quoting some vibration suppression methods.
