摘要
由标量磁位计算圆柱形点缺陷的漏磁场 ,然后计算穿过式线圈及旋转式线圈探测点缺陷的漏磁场产生的感应电动势 ,分析这些检测信号的特性并得出相应的结论。
The magnetic flux leakage of cylindrical point flaw was calculated by scalar magnetic potential method. The potential induced by the magnetic flux leakage of point flaw detected by passing through coil or revolving coil was calculated. Conclusions were obtained by analyzing the characters of the testing signals.
