Finite Element Analysis of Zirconate Titanate Ceramics Piezoelectric Effect

Abstract

The ceramic material of lead zirconate titanate has positive piezoelectric effect; Its mechanical energy can be converted to electrical energy. Finite element model is established for piezoelectric ceramic material, in addition that the transition between force and electric is simulated numerically by the analysis function of force-electric coupling field of ANSYS. We obtain the relationship between output voltage and external force, besides the relationship between different heights and the output voltage within the piezoelectric model. It indicates that pressure is proportional to the output voltage value, and it verifies the correctness of theoretical analysis. These provide a reference for the project application of piezoelectric materials.
