摘　　要：超声波检测是常用的无损检测方法,但超声波传播复杂,检测结果抽象。为使检测结果的评判更具客观性,或是开发新技术新工艺,都需要制作大量的模拟试块进行对比,浪费资源和时间。为对比检测结果及有效开发新技术新工艺,引入有限元分析软件ANSYS,对声波传播进行仿真计算。结果表明,有限元计算可直观地反映波的传播过程和声场特性,仿真模拟试块的作用。为缺陷评判提供理论数据和模型参考,提高评判的准确性;为新技术、新工艺的高效开发提供依据,是研究超声检测技术的有力工具。Ultrasonic test is a generally used NDT method, but the results are often very abstracted because of the complex transmission path of ultrasonic. Whenever a new technique is invented or experiment results need to be proved objectively, many calibration blocks must be made, which means a serious waste of time and resources. Finite element method software ANSYS is a widely-used tool to develop new technique or to veri/y the test or experiment results. In this paper the finite element method software ANSYS was applied to simulate the ultrasonic paths. The result shows that acting as simulating calibration blocks, ANSYS software can exhibit ultrasonic paths and the characteristics of sound field intuitively. The ANSYS software is a helpful and powerful tool to study ultrasonic technology, which can not only provide the basis for the design and development of new technique and technology, but gives theoretical and simulating references for defect assessment.
