Title: One-dimensional analysis of piezoelectric transducers based on Thevenin theorem
Author: Arnold, FJ
Abstract: In this work, a method of analysis of piezoelectric transducers is shown. This method is based on the simplification of Mason's equivalent electric circuit. An adaptation of Thevenin theorem has been employed to study the behavior of piezoelectric transducers used as transmitters (electric into mechanic energy conversion). This study was restricted to transducers with a typical configuration employed in high power applications. The transducers were one-dimensionally modeled, considering only longitudinal vibration modes. An equivalent electric circuit was obtained and computationally simulated. The experimental and calculated results show a good fitting. Features related to the simplification of the model employed and their feasibility for teaching are discussed.
