摘要
振动法是滚动轴承最重要的故障诊断方法,其核心在于有效抽取表征故障的特征值。本文重点从信号处理的角度出发,围绕原理、特点及适用范围,对国内外基于振动法的故障诊断方法进行了比较、总结与展望。
Vibration analysis, aiming to effectly extract the feature values of characterize fault, is the most common method in fault diagnosis of rolling bearings. This paper has compared, summarized and prospected the fault diagnosis method the po method based on vibration in demostic and foreign from nits of signal processing, principle, features and scope
