摘要

摘要

En 中文
涡流检测（ECT）被广泛应用于导电材料结构的检测与评估。近年来，为提高ECT传感器的可靠性和灵敏度，已做出显著努力，包括开发基于聚酰亚胺基板的新型柔性涡流传感器阵列。这些探头因具有柔性，可适应不平整表面。然而，这些探头仍存在失效情况。在本工作中，我们提出了一种具有柔性基板材料的可拉伸EC传感器阵列探头，该探头设计用于变形并贴合复杂表面。开发了一个3D仿真模型，用于研究探头可拉伸性对缺陷检测的影响。制造了探头原型并进行了测试。实验结果表明，所提出的探头成功检测了弯曲管道（弯曲半径为6英寸）上的点蚀缺陷（半径2 mm，深度0.5 mm），而柔性探头此前在该场景下曾失效。
