| 中文摘要: |
| 基于大量实验及波形分析，给出钢丝绳断丝事件的声发射（ＡＥ）定量化表征形式．采用类内类间距离和二维图示方法综合选择ＡＥ特征，并根据其分布情况建立起基干Ｆｉｓｈｅｒ准则的分段线性分类器，以实现断丝事件的自动检测． |
| 英文摘要: |
| Based on large quantity of experiments and waveform analyses, quantitative acoustic emission(AE) signature is achieved for wire breakage in a steel rope. By concur- rently using the measure of within-class and between-class variances and the method of two-dimensional plot, AE features are selected for classification. According to distribution of AE parameters,a piecewise linear classifier is designed with the Fisher discriminate analysis, such that wire breakage can be detected automatically. |
