轴承故障的振动监测与灰色诊断

Vibration Monitoring and Grey Diagnosis of Bearing Faults

根据不同状态下轴承的时序波形和频谱图,提取八个轴承状态特征参数。利用灰色关联分析方法,对受试轴承的状态和故障程度进行分类识别。附图3幅,参考文献5篇。

Baseel on the time squence waveform and frequency spectra of bearing vibration under various working conditions, the eight state characteristic parameters are drawn out by use of Grey Relational analysis, the state and fault levels of test bearings are classified and identified .
