摘要
磁致伸缩超声导波技术因其可进行长距离快速检测的优势受到了国内外学者的极大关注。导波不需要对待检测管道的表层进行特殊处理并且可以对高温环境下和表面存在一定厚度保护层的被测物进行在线检测。目前,在充分发挥磁致伸缩导波自身优势的基础上,通过与其他新技术相结合、并应用新的建模方法和信号处理方法,磁致伸缩导波的功能已变得日益强大。以近十几年的文献为基础,从磁致伸缩的原理与模型、传感器及实验研究、信号处理和磁致伸缩导波技术的工程应用几方面对磁致伸缩导波的研究现状和最新进展进行了综述并对磁致伸缩导波检测的发展前景进行了展望。
Magnetostrictive ultrasonic guided wave technology has attracted great attention of scholars both at home and abroad because of its advantages of long distance and rapid detection.Guided waves do not need special treatment for the surface of the detection pipeline,and can detect the detected objects in the high temperature environment and the surface with certain thickness protection layer.At present,based on the advantages of magnetostrictive guided waves,the functions of magnetostrictive guided waves have become increasingly powerful by combining with other new technologies,and applying new modeling methods and signal processing methods.Nearly ten years of literature as the basis,engineering application of guided wave technology from several aspects,the principle and model of the magnetostrictive sensor and experimental research,signal processing and the research status of the magnetostriction of magnetostrictive guided waves and the latest progress and development prospect of magnetostrictive guided wave detection is prospected.
