该装置采用全油浸耦合,用聚束探头检测近表面缺陷,用表面波检测表面裂纹,用计算机化c扫描定量缺陷尺寸。
By oil immersion coupling. the system can be used to detect near surface defects with focussing probe. find surface cracks with surface wave probe and determine defect size with computerized C-scan.
分析了探头调整时脉冲回波信号的变化特点,在实验的基础上构建了声束入射角与表面波时域特征值间的关系模型。
Using the characteristics of pulse echo singal during the probe adjustment, a relation model between angle of incidence and time-domain eigenvalue of reflect wave signals was proposed.
