Abstract

The integrity of plate structures in numerous facilities and vehicles is essential for ensuring safety. Guided wave testing is a prominent non-destructive testing (NDT) technique, especially for wide plate or long pipe structures. It can be related to tomography techniques to visualize defect information. One way to obtain data for tomography is through experimentation. However, a numerical approach, such as a computational simulation, could also be a feasible option because it can efficiently handle various defect cases. In this study, a dynamic analysis was performed to acquire the guided wave signal on a plate containing a wall-thinning defect, for which previous studies were insufficient. Acquired signals are compared to each other, and studies have demonstrated that wall-thinning defects can be visualized. This approach to signal data acquisition is expected to enhance the efficiency of data collection in several fields, such as machine learning implementation in NDT.

基于数值模拟导波信号采集的板结构薄壁缺陷断层成像技术

摘要在众多设施和车辆中，板结构的完整性对确保安全至关重要。导波检测是一种重要的无损检测（NDT）技术，尤其适用于宽板或长管道结构。它与断层扫描技术相关，可将缺陷信息可视化。获取层析成像数据的一种方法是通过实验。然而，数值方法（如计算模拟）也是一种可行的选择，因为它可以有效地处理各种缺陷情况。在本研究中，对含有薄壁缺陷的平板进行了动态分析，以获取导波信号。将采集到的信号相互比较，研究表明可以直观地看到薄壁缺陷。这种信号数据采集方法有望提高多个领域的数据采集效率，例如无损检测中的机器学习实施。图形摘要
