径向极化压电陶瓷管建模与仿真
Modeling and simulation of radial polarized piezo tube
摘要
Abstract
Based on plane strain hypothesis, radial displacement formula of polarized piezo ceramic cylinder excited by radial electric fieldwas derived. Radial polarized piezo ceramic cylinder, which is actuator of squeeze-mode piezoelectric inkjet printhead, perform mainly radial deformation under radial external electric field. Finite element (FE) simulationwas also carried out using the software of ANSYS 14.0. Inner surface radial displacements of different piezo tubeswere analyzed using the two methodsat 100 V. The difference between results of the analytic formula and FE simulation is less than 5%. Consistent results of two different methods verify qualification of the derived formula. The analytic model could be used to predict the response of squeeze-mode inkjet printer under external electric field, reduce design costs and improve design reliability and efficiency.关键词
