Analysis on Dynamic Piezoelectric Coupling Characteristics of PZT-4

Abstract:

Structural behavior of piezoelectric stacks has a great impact on electromechanical conversion efficiency of highway piezoelectric generators. In this paper, a single piezoelectric ceramic chip in piezoelectric stack structure was regarded as the object of study to construct the ANSYS model of a single piezoelectric ceramic entity. The selection of SOLID5 makes the piezoelectric ceramic chip into the grid cube and by the coupling field, maintains five aspects of static and dynamic piezoelectric coupling characteristic simulation analysis respectively, including static analysis, modal analysis, harmonic analysis, transient analysis and circuit simulation analysis. The results of all the analyses for the optimal structure design of highway piezoelectric generators are to provide a reference.
