Differential excitation eddy current sensor testing for aircraft engine blades defect

  • 摘要: 针对某型号飞机发动机涡轮叶片上预制的微裂纹缺陷进行了检测研究.基于涡流检测技术设计并研制了一种尺寸小、灵敏度高的差激励探头,应用有限元分析软件开展了叶片微裂纹缺陷仿真分析.为了实现叶片的自动高效检测,设计并采用数控多自由度扫查台来控制采集过程,实现了对叶片表面裂纹缺陷的快速扫查检测.采集信号经过信号调理电路,A/D转换后输入计算机,完成信号的保存、处理和输出.通过对比实验结果与仿真结果发现,研制的差激励式涡流传感器可以有效地实现对叶片类零件表面微裂纹位置的判定,对涡轮叶片类零件微缺陷早期诊断评估具有一定的现实和借鉴意义.
