Bearing fault diagnosis under non-stationary conditions based on a speed signal resonance component demodulation algorithm

Ming Ye,
Xiaojun Zhang,
Jiaqiang Yang

Abstract: This paper proposes a novel bearing fault diagnosis indicator, the resonance component, for motor speed signals. The speed signal was modulated into a higher-frequency band using a double-inertia system, and the bearing fault information was carried and reserved in this high-frequency resonance component. Variational mode decomposition was then used to separate the components unrelated to the resonance based on the parameters optimized using the artificial bee colony algorithm. After envelope demodulation and … Show more

“…In [19], an enhanced Vold-Kalman filter for signal decomposition was presented using separated cosine and sine kernels. VMD was used in [20] to separate the components unrelated to the resonance based on the parameters optimized using the artificial bee colony algorithm. A novel two-level chirp mode decomposition approach was proposed in [21] to decompose complex AM-FM signals with strong noise.…”
