A low frequency rolling bearing fault diagnosis method based on local projective noise reduction;

基于局部投影降噪的低頻軸承故障診斷

According to characteristics of both the vibration signals and the stator currents when appering a fault in the rolling bearing of the induction motor,Park vector module signal of the three-phase current is calculated,and the envelope of vibration signals from the rolling bearing of the motor is analyzed.

根據(jù)感應(yīng)電機軸承發(fā)生故障時的振動信號特性以及定子電流特性,求出三相電流的Park矢量模信號,并將其與電機滾動軸承振動信號經(jīng)解調(diào)處理后的包絡(luò)信號進行融合分析,可以從振動信號與電流信號的融合譜圖中有效地提取軸承故障特征信息,并將其作為故障識別的依據(jù)。

Because the signal from rolling bearing is non-linear and non-Gaussian, here, the bispectrum analysis method is applied to the different types of rolling bearing and the different serious extent for the same bearing fault.
