变壁厚薄壁筒体超声缺陷特征研究

Study on the Ultrasonic Testing Algorithm for the Thin-Walled Pipes with Variable Wall Thickness

针对变壁厚薄壁简体板波特征,提出利用数据分段处理与相关系数相结合的方法,较好地实现了对变壁厚薄简体在线自动无损检测。

An adjoint way of data sementation and correlation coefficient for ultrasonic lamb wave of the thin-walled pipes with variable wall thickness was put forward,and the online insepection of the thin-walled pipes with variable wall thickness was accomplished well.
