Abstract

A well-designed matching layer attached to a transducer is an effective method to obtain broad bandwidth. In practical applications, the optimal material parameters and geometric parameters for the matching layer are required to be calculated precisely. In this paper, we propose a fluid–structure interaction model for vibro-acoustic analysis of the transducer. An analytical solution to determine the electrical impedance of a transducer with a matching layer immersed in water is derived. The influence of matching layer on the performance of the transducer is demonstrated clearly. To verify the proposed model, a 1–3 piezoelectric composite transducer with a matching layer according to the our proposed model is fabricated. Consequently, the theoretical model we proposed can accurately predict the electrical impedance of the transducer with a matching layer. According to the model, the optimal thickness and acoustic impedance for the matching layer to expand the conductance bandwidth of the transducer can be figured out accurately. In addition, our proposed model also provides a reference for designing a transducer with a matching layer.

1-3压电复合换能器上匹配层的振动声分析

设计良好的匹配层附着在换能器上是获得宽带宽的有效方法。在实际应用中，需要精确计算匹配层的最优材料参数和几何参数。本文提出了一种用于换能器振动声分析的流固耦合模型。导出了一种确定浸入水中的具有匹配层的换能器电阻抗的解析解。分析了匹配层对换能器性能的影响。为了验证所提出的模型，制作了一个具有匹配层的1-3压电复合换能器。因此，我们提出的理论模型可以准确地预测具有匹配层的换能器的电阻抗。根据该模型，可以准确计算出扩展换能器电导带宽的匹配层的最佳厚度和声阻抗。此外，该模型还为设计具有匹配层的换能器提供了参考。

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.
