非接触式超声能量从受到强制振动的压电圆柱体或盘传递到压电接收器提供了将能量安全地传递到传感器和设备的能力，这在不同的应用中具有很大的兴趣。支持超声能量传递的物理过程包括在发射元件处的压电产生的振动、在接收元件处的弹性振动的压电转换、声波传播以及在发射元件和接收元件的表面处的声学-结构相互作用。考虑到这些过程，我们提出了一个实验验证的多物理模型，填补了知识空白，准确地表示压电盘的流体加载响应，通常用于超声能量传递作为一个圆柱形发射源圆柱形接收器组合。首先，我们利用广义汉密尔顿原理推导出控制方程，并利用有限元法求解。其次，我们计算了共振条件下由于声-结构相互作用引起的表面压力分布。然后，我们使用的模式形状和表面压力分布从有限元模型结合矩阵控制方程开发一个降阶模型与量化的电抗性和电阻性部分的声辐射阻抗。然后，通过比较具有不同纵横比的四种不同压电盘的电阻抗，实验验证了所开发的降阶模型。我们还讨论了如何利用所提出的方法来开发压电接收器的降阶模型。所提出的方法和降阶模型允许精确识别的关键参数，支配压电盘之间的声能传递，这是设计高效的超声声能传递系统的关键。
Contactless ultrasound energy transfer from a piezoelectric cylinder or disk subjected to forced vibrations to a piezoelectric receiver offers the capability of safely transferring energy to sensors and devices, which is of great interest in different applications. Physical processes supporting ultrasonic energy transfer include piezoelectric-generated vibrations at a transmitting element, piezoelectric transduction of elastic vibrations at a receiving element, acoustic wave propagation, and acoustic-structure interactions at the surfaces of the transmitting and receiving elements. Considering these processes, we present an experimentally-validated multi-physics model that fills a knowledge gap in terms of accurately representing the fluid-loaded response of piezoelectric disks, usually used in ultrasonic energy transfer as a cylindrical transmitting source-cylindrical receiver combination. First, we derive the governing equations using the generalized Hamilton's principle and solve them using the finite element method. Second, we compute the surface pressure distribution due to acoustic-structure interactions under resonance conditions. We then use the mode shapes and surface pressure distributions obtained from the finite element model in conjunction with the matrix governing equations to develop a reduced-order model with quantified reactive and resistive parts of the acoustic radiation impedance. The developed reduced-order model is then experimentally validated by comparing the electrical impedance of four different piezoelectric disks having various aspect ratios. We also discuss how the proposed approach should be utilized to develop reduced-order model for piezoelectric receivers. The presented approach and reduced-order model allow for accurate identification of critical parameters that govern acoustic energy transfer between piezoelectric disks, which is crucial for designing efficient ultrasonic acoustic energy transfer systems.
