查询词典 tooth key

The paper presented a method of detecting long-range correlation in a signal--detrended fluctuation analysis and applied it to diagnose gear faults. Two key problems, i.e. scaling range and polynomial order of fitted trend, were discussed. Scaling exponent was extracted to be as a detector for diagnosing five types of gear faults, their were normal, spalling, tooth broken, wearing and cracking.

探讨了一种检测非平稳信号中长程相关信息的方法--利用去趋势波动分析（detrended fluctuation analysis，DFA）方法来诊断机械故障，着重研究DFA的尺度范围选择、趋势拟合阶数选择等关键问题，提取尺度指数作为诊断的特征参数，应用于齿轮的正常、剥落、断齿、磨损、裂纹等五种状态诊断，正确率达96％以上。
