摘要

本文介绍了一种用于距离测量的双晶片弯曲压电超声换能器(简称PUT)。介绍了一种基于低烧结压电陶瓷PMN-PNN-PZT的双晶片弯曲PUT材料，该材料具有高压电常数(d/sub 33/>680pC/N)和高机电耦合系数(K/sub p/=0.70/spl sim/0.73)。对其谐振模态进行了数值分析和有限元分析。采用先进的激光扫描测振仪测量了其共振模式的位移幅值分布。它极大地帮助了我们设计和分析换能器。

Design and analysis of a piezoelectric ultrasonic transducer for distance measurement

This paper describes a kind of bimorph flexural piezoelectric ultrasonic transducer (abbreviated as PUT) for distance measurement. A bimorph flexural PUT based on low-sintering piezoelectric ceramics PMN-PNN-PZT, which have high piezoelectric constant (d/sub 33/>680pC/N), high electromechanical coupling factor (K/sub p/=0.70/spl sim/0.73), was introduced. The numerical and finite element analysis (abbreviated as FEA) of its resonant modes were investigated. An advanced laser scanning vibrometer has been used to measure the displacement amplitude profiles of their resonant mode. It has greatly helped us to design and analyze transducers.
