如何对复杂功率超声换能器耦合振动系统的声波进行调控，设计高性能的换能器系统，一直都是功率超声领域亟待解决的难题。研究发现，在换能器系统内部引入各种缺陷，可以在一定程度上改善换能器耦合振动系统的性能。但损耗大、频带窄、对结构参数敏感等缺点限制了缺陷型声子晶体换能器耦合振动系统的进一步实际应用。为了改善缺陷型声子晶体换能器耦合振动系统的局限，有效降低能量损耗，提高能量传输的效率，论文在换能器耦合振动系统内引入既具有能量局域化效应的拓扑缺陷结构又具有高能量传输效率的声表面结构。通过灵活地设计声表面结构和拓扑缺陷的几何尺寸参数，可以对换能器耦合振动系统的振动进行有效调控，从而满足换能器耦合振动系统功能方面的不同需求。但表面结构和拓扑缺陷结构的设计参数过多，会成倍地增加设计的复杂度，大幅降低设计成功率，为此，利用数据分析技术建立了系统性能预测模型，不仅可以提高设计效率和成功率，还能够为换能器耦合振动系统性能的调控提出客观和准确的依据。How to regulate the sound waves in the coupled vibration system of complex power ultrasonic transducers and design high-performance transducer systems has always been an urgent problem in the field of power ultrasound. Research has found that introducing various defects within the transducer system can improve the performance of the transducer coupled vibration system to a certain extent. However, the drawbacks of high loss, narrow frequency band, and sensitivity to structural parameters limit the further practical application of defect type phononic crystal transducer coupled vibration systems.
In order to improve the limitations of the coupled vibration system of defect type phononic crystal transducers, effectively reduce energy loss, and improve the efficiency of energy transmission, this paper introduces a topological defect structure with energy localization effect and a sound surface structure with high energy transmission efficiency into the coupled vibration system of the transducer. In this study, the acoustic surface structure and topological defect structure were used to excite defect states with energy localization effects and high energy transmission efficiency surface states, effectively regulating the vibration of the transducer coupled vibration system, and constructing a transducer coupled vibration system with high quality factor, low loss, and high energy transmission efficiency. By flexibly designing the geometric size parameters of the acoustic surface structure and defects, the vibration of the transducer coupled vibration system can be effectively controlled, thereby meeting the different functional requirements of the transducer coupled vibration system.
However, due to the excessive design parameters of surface structure and topological defect structure, the complexity of the design will be multiplied, greatly reducing the success rate of the design. Therefore, this study uses data analysis technology to establish a performance prediction model for the transducer coupled vibration system, in order to achieve accurate prediction of system performance and change the shortcomings of low design efficiency and low success rate brought by traditional empirical trial and error methods.
In order to verify the effectiveness of the research, the paper simulated and experimentally processed the coupled vibration system of the transducer. The simulation and experimental results indicate that the acoustic surface structure and topological defect structure can effectively regulate sound waves to improve the performance of the transducer coupled vibration system.-
