飞机多层结构中深层缺陷的定量评估是目前航空无损检测领域面临的一个难点问题，传统无损检测方法需要对飞机结构拆卸后进行检测，这样既增加了费用又无法满足飞机外场检测的需求，远场涡流技术由于不受集肤效应的限制，其可实现原位检测的优点成为解决此难题的有效途径。在分析了非磁性平板构件脉冲远场涡流检测技术所存在问题的基础上，通过设计基于UTC结构的传感器使得平板构件检测中也产生了远场效应。同时，对 UTC 结构中材料属性、UTC结构长度和厚度对检测结果的影响进行了仿真分析，得到了其优化设计的准则。

On the basis of analyzing the difficulties of RFEC used in detecting non-magnetic plate,the re-mote field effectiveness is formed on an obj ect of flat geometry by using a type-U component.The princi-ples of optimization design are obtained through analysis of the influence of materials of the UTC,the length of the UTC and the thickness of the UTC.The research of this paper is of some important theoreti-cal meaning and practical value for promoting the application of the RFEC technique and to the detection of the nonmagnetic metal plate.
