摘要

由于各种来源的材料退化，工业部件的故障是不可避免的，因此为了结构安全，必须进行持续的监测和及时的检查。本文采用近年来发展起来的瞬态涡流振荡(TECO)方法来检测不锈钢板的壁厚变薄。与传统的涡流测试阻抗平面数据不同，采用了一种新的解释方法，利用s域参数来识别厚度变化。此外，还分析了时间和频谱特征，以便更深入地了解结果。衰减时间和谐振频率是讨论评价壁厚的基础。

Study of Change in Stainless Steel Plate Thickness using S-Domain Parameters Derived from Transient Eddy Current Oscillations Method

Failures in the industrial components are unavoidable due to material degradation from various sources, thus continuous monitoring and timely inspection is mandatory for structural safety. In the present study, the recently developed Transient Eddy Current Oscillations (TECO) method is used to detect wall-thinning in a stainless-steel plate. Unlike the conventional Eddy Current Testing impedance plane data a new interpretation method has been implemented to identify a thickness variation using the S-domain parameters. Furthermore, time and frequency spectral features are analysed to get more insight into the results. The decay time and the resonant frequency are the basis for the discussion to assess the wall thickness.
