摘要
将物理模型置于水中,利用声波透射法在不同测距和深度的情况下,对比各组数据的波速、波幅、波形等几个因素分析超声波法的缺陷识别能力。同时也讨论了影响声波透射法的缺陷识别能力的主要因素,初步总结了不同测距情况下声波透射法对同一几何大小缺陷的辨别能力。
The physical model is placed in water,and the sound-transmission method is used to analyze the defect recognition ability of ultrasonic method by comparing the wave velocity,amplitude and waveform of each group with different distance and depth.At the same time,the main factors influencing the defect recognition ability of the acoustic transmission method are also discussed.The ability of the acoustic transmission method to identify the same geometric defect is summarized.
