针对涡流检测中穿过式探头对某些缺陷不敏感、检测灵敏度较低等问题 ,对探头线圈的结构进行了设计 ,由于结构参数较多 ,采用正交试验方法进行了规划。对重新设计的一组探头进行了试验对比 ,从中选出检测效果较好的探头结构方式。
In order to solve the problems that the through-type probe is not sensitive to certain defects and the detection sensitivity is low, the structure of the probe coil is designed. Due to the large number of structural parameters, the orthogonal test method is used for planning. A redesigned set of probes were tested and compared to choose the better detection of the probe structure.
