铁道货车无轴箱滚动轴承故障诊断中特征提取和分类方法的探讨

Discussion about the Characteristic Obtaining and Classifying Method in the Fault Diagnosis of Boxiess Rolling Bearings onRailway Wagons

本文从滚动轴承故障诊断这一主题出发，讨论最大熵谱估计在滚动轴承状态特征提取中的应用和由统计模式识别来实现分类的方法。

This paper begins with the fault diagnosis of rolling bearings. Discussed here are the application of the maximum entropy spectrum estimation in obtaining of state characteristic of rotting bearings and the classifying method with the use of statistic pattern recognition.
