摘　　要：采用涡流方法检测某型飞机轮毂弧面时,信号判别困难。通过大量的轮毂涡流检测试验,找出了缺陷信号与干扰信号的微小区别。通过二元函数知识分析判断,可以把缺陷信号有效地识别出来。经试用,该方法能较为可靠地识别疲劳裂纹信号。When the method of eddy current testing was adopted to detect a certain type of aircraft wheel hub, for the existence of cambered surface located at the detected part, this caused the difficulty of signal discriminate. Through a large number of the hub tested by the way of eddy current, the differenee between the flaw indication and jamming signal was found. The results of analysis by using math function knowledge show that this recognition method can be more reliable in the use of detecting the signal of fatigue crack.
