本文用全息干涉计量术对两类换能器及长方片状、图片状、管状等三类压电元件作了较全面、系统的振动分析;提出了弯曲振动与纵向振动并存时的条纹解释方法及比较同类型或不同类型元件压电效应优劣的电场-比振幅法,为换能器的设计和提高压电元件的性能提供了可靠的、有价值的全息干涉条纹图样和有关数据以及方法.
In this paper, holographic interferometry is used to make a comprehensive and systematic vibration analysis of two types of transducers and three kinds of piezoelectric elements, such as rectangular sheets, picture sheets and tubular sheets. The streak interpretation when bending vibration and longitudinal vibration coexist Methods and comparison of the same type or different types of elements of the piezoelectric effect of the pros and cons of the electric field - specific amplitude method for the transducer design and improve the performance of piezoelectric components to provide a reliable and valuable holographic interference fringe patterns and related data and method.
