摘要

摘要: 超声导波是近年来新兴的无损检测技术。相比传统的超声检测、漏磁检测，它可提供大范围、全面高效的检测，因此越来越受到关注，尤其是在管道检测方面。但超声导波的传播与反射特性复杂，因此利用有限元仿真指导实验设计并验证实验结果非常必要，而如何保证有限元模型的正确性是目前有限元仿真研究的一个重要问题。以时间子步为例，分析了仿真参数对超声导波检测管道缺陷仿真模型的影响，提出并定义多量化评估指标实现了仿真参数最优值的确定。根据仿真与实验结果的对比分析，验证了仿真参数优化的有效性。

Abstract: Ultrasonic guided-wave (UGW) is an emerging non-destructive testing technique in recent years. Compared with the conventional inspection techniques, such as ultrasonic inspection and magnetic flux leakage testing, the UGW can enable long-range, comprehensive and efficient inspection. It thus attracts more attention, especially for pipe inspection. However, the propagation and reflection of guided wave are complicated, and it is always essential to introduce finite element analysis (FEA) into UGW research for guidance and verification of experimental results. How to guarantee the accuracy of FEA model is an important problem. In this paper, with number of time substeps as an example, the effects of simulation parameters on simulation models are analyzed, and the method for selecting the optimal simulation parameters with quantitative evaluation criteria is proposed. The comparison results between simulation and experimental results verify that the method is effective for optimizing simulation parameters.
