Simulation and Visualization of the Radiated Acoustic Field of Ultrasonic Transducers

摘要

摘要: 了解超声换能器声场的分布对于检测精度和灵敏度的提高、检测工艺参数的优化都起着至关重要的作用。为了更直观地分析超声换能器的声场，提高对超声波产生和传播机理的理解，利用多元高斯声束模型，对超声换能器辐射的声场进行了计算机模拟和可视化，开发了具有良好用户界面接口的声场模拟程序。试验结果表明，模拟结果能够比较准确地反映声场的实际分布。

Abstract: Knowing the acoustic field distribution of ultrasonic transducers is of vital importance to the improvement of testing accuracy and sensitivity and the optimization of inspection parameters. In order to analyze the acoustic field of ultrasonic transducers more directly and to understand better the generation and propagation mechanism of ultrasound, the radiated acoustic field of ultrasonic transducers is simulated and visualized by means of multi-Gaussian beam model. Moreover, an acoustic field simulation program is developed featured with a friendly graphic user interface. The experimental results demonstrate that the simulation can represent the distribution of the acoustic field actually and exactly.
