An adaptive cross-validation thresholding de-noising algorithm for fault diagnosis of rolling element bearings under variable and transients conditions

HIGHLIGHTS

• who: An Adaptive Cross-Validation Thresholding et al. from the of Mechanical and, Wenzhou University, Wenzhou, China have published the research: An Adaptive Cross-Validation Thresholding De-Noising Algorithm for Fault Diagnosis of Rolling Element Bearings Under Variable and Transients Conditions, in the Journal: (JOURNAL)
• what: In this work, a simulated faulty signal with SNR of 0 dB is given and its waveform of raw signal is shown in Fig 7(a).
• how: In this section the proposed method is tested for the ball defection. STFT is applied to calculate the TFR of . . .
