摘要
提出了用缺陷回波信号包络作为超声检测的缺陷模糊识别模型并根据此模型建立缺陷模糊识别用的缺陷模糊子集的方法。给出了用实验方法建模的结果和缺陷模糊模式识别应用示例。
The fuzzy recognition model of flaw based on the signal envelope of flaw echoes in ultrasonic in-spection and the establishment of fuzzy subsets of the flaws detected according to the model are developed. The experimental results of model establishment and application example of recognizing flaws by fuzzy pattern recog-nition are also given.
