Abstract

In this article, the actuating performance for functionally graded piezoelectric materials (FGPM) using the \(d_{33}\) mode actuation is investigated. The material properties vary continuously across the thickness direction, according to a fraction volume power law distribution, so that top and bottom surfaces consist of pure PZTG and the mid surface is composed of pure aluminium. The percolation phenomenon is taken into account. The optimization of the interdigitated electrode (IDE) design for FGPM is performed using finite element analysis. Several design parameters (electrodes number, width and spacing) are considered to improve the produced displacement for a cantilever plate, and the use of multilayered IDE is intended. Results are discussed for several distributions of the components in the FGPM thickness. A comparison with the \(d_{31}\) mode actuation is presented.

交错电极功能梯度压电材料的致动性能

本文研究了功能梯度压电材料(FGPM)在\(d_{33}\)模式下的致动性能。根据分数体积幂律分布，材料性能在厚度方向上连续变化，因此上下表面由纯PZTG组成，中表面由纯铝组成。考虑了渗流现象。采用有限元分析方法对FGPM的插指电极(IDE)设计进行了优化。考虑了几个设计参数(电极数、宽度和间距)来改善悬臂板的产生位移，并打算使用多层IDE。结果讨论了组分在FGPM厚度中的几种分布。并与\(d_{31}\)模式作了比较。

期刊介绍： While ceramics have traditionally been admired for their mechanical, chemical and thermal stability, their unique electrical, optical and magnetic properties have become of increasing importance in many key technologies including communications, energy conversion and storage, electronics and automation. Electroceramics benefit greatly from their versatility in properties including: -insulating to metallic and fast ion conductivity -piezo-, ferro-, and pyro-electricity -electro- and nonlinear optical properties -feromagnetism. When combined with thermal, mechanical, and chemical stability, these properties often render them the materials of choice. The Journal of Electroceramics is dedicated to providing a forum of discussion cutting across issues in electrical, optical, and magnetic ceramics. Driven by the need for miniaturization, cost, and enhanced functionality, the field of electroceramics is growing rapidly in many new directions. The Journal encourages discussions of resultant trends concerning silicon-electroceramic integration, nanotechnology, ceramic-polymer composites, grain boundary and defect engineering, etc.
