Abstract

Applications of guided waves in various fields of engineering and science rely on elastic wave emitters for wave generation. Accurate prediction and understanding of the far-field responses of these wave emitters are crucial for the reliable and efficient application of guided waves-based technologies. In this paper, we propose a novel semi-analytical framework capable of predicting the far-field response of complex wave emitters of arbitrary shape and internal structure in any type of substrate. This framework is general, and is not confined to specific methods, enhancing its versatility. We applied the proposed semi-analytical framework to predict the directivity patterns of two different macro-fiber composite transducers, accurately modeled using their exact topologies. The framework’s validity was experimentally confirmed by comparing the predicted directivity patterns with the results obtained from experimental measurements.
预测复杂弹性波发射器远场响应的半分析框架。
导波在各个工程和科学领域的应用都依赖于弹性波发射器来产生波。准确预测和理解这些波发射器的远场响应,对于可靠、高效地应用基于导波的技术至关重要。在本文中,我们提出了一个新颖的半分析框架,能够预测任何类型基底中任意形状和内部结构的复杂波发射器的远场响应。该框架具有通用性,不局限于特定的方法,从而增强了其通用性。我们应用所提出的半分析框架预测了两种不同的宏纤维复合传感器的指向性模式,并使用它们的精确拓扑结构进行了精确建模。通过将预测的指向性模式与实验测量结果进行比较,实验证实了该框架的有效性。
