摘要:T(0,1)模态导波由于其良好的频散特性被广泛应用于长距离管道无损检测中,管道横向、纵向缺陷的定量检测对管道无损检测技术的发展具有重要意义。本文使用有限元软件ABAQUS对铝制管道不同尺寸缺陷进行建模并激励T(0,1)模态导波,采用脉冲回波的方法定位缺陷,得到反射系数与横向缺陷截面损失的关系以及纵向缺陷长度对缺陷回波信号结构的影响。使用MSGW磁致伸缩导波实验平台设计实验,检测具有不同横向、纵向尺寸缺陷的铝管,实验结果与仿真结果在允许的范围内基本吻合。研究表明,反射系数随缺陷横截面损失的增大呈接近线性的增大趋势,缺陷回波信号由缺陷前后端面的反射信号叠加形成。

Abstract: The T(0,1) mode guided wave is widely used in long term NDT of the pipeline. The reflection characteristics of T(0,1) mode guided wave for an aluminum pipe with both circumferential and axial defects are discussed in this paper. Three-dimensional finite element models of cracked pipes are established in the software package ABAQUS/EXPLICIT for investigating the reflection characteristics from defects with different circumferential and axial extent. The T(0,1) mode is incident from one end of the pipe and the defect is located by using the pulse echo method. The corresponding experiments are done with MSGW to verify the simulation results. It has been found that the reflection coefficients have nearly linear relation with the section loss, and that the reflection signals is the joint result of interference between reflected signals from both front and back ends of the defect.

131基于时频分析及匹配追踪的超声导波管道缺陷检测算法研究

(浙江大学)

摘要:超声导波对管道缺陷进行检测定位过程中,接收到的导波信号往往夹杂着大量的噪声信号使得管道的缺陷信号淹没在噪声之中而难以判断。传统的数字带通滤波、自适应滤波、小波阈值滤波对导波信号噪声的滤除具有一定的作用,但对小缺陷信号仍然无法很好地检出。本文提出一种结合复Morlet小波时频分析及基于Gabor字典的匹配追踪算法相结合的方法,先对导波信号进行连续小波变换,再用匹配追踪算法分解逼近信号,最后经过叠加各尺度信号重建出时域信号。通过磁致伸缩导波检测钢管上缺陷的实验,对比小波阈值滤波方法,验证了该滤波算法能够较好地提高缺陷的检测能力和信噪比效果。

131Research on algorithm of defect detection in pipes using ultrasonic guided waves based on time-frequency analysis and matching pursuit

(ZheJiang University)

Abstract: Defect detection and location in pipes using ultrasonic guided waves, the defect signal in pipes will be overwhelmed by noise and difficult to distinguish as the received guided wave usually mixed with lots of noise. Traditional digital band-pass filteradaptive filterwavelet threshold de-noising has a certain effect on filtering the guided wave signal noise. However, it is still hard to detect the small defect. In this research, we proposed a method which combining complex Morlet wavelet time-frequency analysis and matching pursuit algorithm based on Gabor dictionary. Guided wave signal will be transformed by continuous wavelet first, then matching pursuit algorithm will be used to decompose and approach the signal, the signal will be reconstructed via superimposing on each scale signal at last. The experiment of magnetostrictive guided wave detection of defects in pipe demonstrated that the filter algorithm we proposed is effective in defect detection and raising the signal to noise ratio.
