基于磁致伸缩效应的钢管导波检测可行性
Feasibility of Detecting Defects in Steel Pipe Using Guided Waves Based on Magnetostrictive Effect
摘 要
在论述钢管磁致伸缩导波检测原理的基础上，研制了相关实验装置。分析了轴对称布置的线圈和偏置磁场在低频激励时产生的波模式。使用L(0,2)模式对两种人工缺陷进行检测，得到直径>3.5 mm的通孔和深度>1.5 mm的横向刻槽的缺陷反射信号。结果表明磁致伸缩导波用于钢管无损检测是可行的。

Abstract
The principles of testing steel tubes by guided waves based on magnetostrictive effect were introduced. An prototype of experimental system was developed. The modes resulted with stimulating in low frequency range and the axisymmetrical configuration of coils and bias magnetic fields were analyzed. Two types of defects of different sizes were tested using L(0,2) mode. The reflected signal from defects could be identified for through-wall holes of 3.5mm in diameter and above, and notches of 1.5mm in depth and above. The experimental results showed the feasibility of magnetostrictive guided waves in steel tubes testing.
