A Hybrid Time-Frequency Analysis Method for Railway Rolling-Element Bearing Fault Diagnosis
The health condition of rolling-element bearings is important for machine performance and operating safety. Due to external interferences, the impulse-related fault information is always buried in the raw vibration signal. To solve this problem, a hybrid time-frequency analysis method combining ense...
