Far-field eddy current detection and evaluation on inside layer corrosion damage of aircraft multilayer structures

  • 摘要: 飞机多层结构的内部腐蚀具有隐蔽性强的特点,因而难以及时发现,严重威胁飞行安全。利用远场涡流检测技术,针对飞机多层结构的内层损伤,研究了硬铝合金多层结构内层模拟腐蚀缺陷的涡流检测。结果表明:对相位进行分析可以判断缺陷的埋藏深度;结合飞机蒙皮的单层厚度,可以确认缺陷所在蒙皮的层数,根据埋深和层数调用相应的公式,可以获得缺陷的准确信息;远场涡流检测的灵敏度高,可以实现对腐蚀缺陷的定位检测和定量检测。
    Abstract: It's difficult to detect the hidden internal corrosion of multi-layer structure of aircraft is hidden and difficult to detect in time, which seriously threatens flight safety. Aiming at the difficulty of damage detection in multi-layer structure of aircraft, this paper studies the detection of simulated corrosion defects in multi-layer structure of hard aluminium alloy using far-field eddy current detection technology. The results show that the embedded information of defects can be judged by phase analysis. The number of defect layers is confirmed by the single layer thickness of aircraft skin. Then the corresponding formula is invoked according to the buried depth and layers, so as to obtain the accurate information of defects. That is, the far-field eddy current has high sensitivity. It can realize the localization and quantitative detection of corrosion defects.
