摘要

压电陶瓷的剪切振动模态因其独有的剪切形变和高压电常数、高机电耦合系数以及介电常数低等特点,在压电俘能器、新结构复合材料换能器方面有着不俗的表现。通过设计具有特殊结构的过渡层,探索压电陶瓷剪切振动的利用方法,将压电陶瓷产生的剪切振动转化为复合材料的厚度振动,以此来满足水声换能器的要求,进而提高复合材料的压电性。通过有限元分析和实验验证,研究了该设计中结构参数、过渡层材料种类对复合材料整体性能的影响。力求有效提高复合材料的能量转换效率和压电性,并研制出具有较小结构尺寸的低频换能器。

Abstract

The shear vibration modes (d15 mode) of piezoelectric ceramics have many advantages, such as high electromechanical coupling coefficient, generally higher piezoelectric constant, low frequency constant, and dielectric constant.It thus has a good performance in piezoelectric energy collector and new structural composite transducers.The shear vibrations generated by the piezoelectric ceramics were converted into the thickness vibration of the composite with designing a transition layer with a special structure.At the same time, this transition layer meets the requirements to radiate underwater longitudinal wave, and thus improves the piezoelectric properties of composite materials.The impact of the transition layer material types on the overall performance of the composite material was studied through the finite element analysis and experiments.
