| 摘 要： | 建立了小尺度浅层瞬变电磁法检测碳纤维复合材料的计算模型.沿测线将计算模型进行简化,通过Hankel变换求取测点的瞬变电磁响应,组合所有测点的数据获得复合材料的瞬变电磁响应.结果表明:异常与试块缺陷有很好的对应关系,计算精度随测点间距的减小而增加.通过与检测试验数据的对比,分析和验证了计算模型的适用性和精度.

| Abstract: | An computation model is developed that small yardstick and shallow transient electromagnetic method(TEM) is put forward to detect composites.The model is simplified along a measuring line,and transient electromagnetic response of every measuring point is obtained through Hankel transformation,then all data are converted into a profile of composites.The result shows that the comparison between anomaly and specimen flaws shows an excellent agreement,and computational precision improves along with the reductio... |
