Experiment on Velocity and Max Length of Testing in Ultrasonic Guided Wave Inspection Based on Magnetostrictive Technology
摘 要
针对基于磁致伸缩超声导波技术的导波波速及检测长度进行了试验研究。试验中采用干耦合方式, 分别对两种不同材质(不锈钢、合金钢)管道试样进行了超声导波检测。试验结果表明, 分别单向激励64和128 kHz的T(0, 1)模态超声导波在两种不同材质的管道管端位置, 波速及检测长度有着明显的差异。
Abstract
The ability of ultrasonic guided wave inspection of velocity and max length of testing by using the magnetostrictive sensor technology was studied experimentally. Experiments were done to two different materials(stainless steel, alloy steel) pipeline sample, while the sensors were air-coupled to the pipes. The experimental results showed that each one-way 64 kHz and 128 kHz encourage the T(0, 1) mode ultrasonic guided wave of two different materials on the possession of the pipelines end position, velocity and length of the detection had a significant change.
