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。
A method of using the echo envelope of the flaw as the fuzzy recognition model of ultrasonic flaw and establishing the fuzzy subset of the flaw used to identify the flaw based on this model is proposed. The experimental results and the application of fuzzy pattern recognition are given.
