摘要

从微观上系统分析了电致伸缩效应、逆压电效应和铁电效应的位移机理

表明:三种效应的位移机理是根本不同的;压电陶瓷执行器的位移主要是由逆压电效应、铁电效应所引起的

电致伸缩效应对位移的贡献极其微弱

可以忽略不计;单纯的逆压电效应是线性的

而铁电效应则是迟滞非线性的.指出了非180°电畴转向与转向的不完全可逆

分别是造成压电陶瓷执行器非线性和迟滞的根本原因.通过实验研究了驱动电压幅值、驱动电压频率、驱动循环次数及晶片厚度对压电陶瓷执行器迟滞和非线性的影响.

Abstract

The displacement mechanisms of electrostrictive effect

inverse piezoelectric effect and ferroelectric effect are systematically analysed in a microcosmic way

and the results of analyses indicate that the displacement mechanisms of these three effects are totally different; the displacement of piezoelectric ceramic actuators is mainly due to inverse piezoelectric effect and ferroelectric effect; the contribution of electrostrictive effect to the displacement is so little that it can be neglected; pure inverse piezoelectric effect is linear

while ferroelectric effect is hysteretic and nonlinear. It is pointed out that the non 180皌urn of ferroelectric domain and its incomplete reversibility are the essential causes for nonlinearity and hysteresis of piezoelectric ceramic actuators respectively. The influences of driving voltage amplitude

driving voltage frequency

number of driving voltage cycles

and walfer thickness on the hysteresis and nonlinearity of piezoelectric ceramic actuators are studied through expeirments.
