Dynamic Effect of Bearing Wear on Rotor-Bearing System Response
Keyword(s):
A rotor-bearing system is simulated in this study to investigate the effect of worn journal bearings on the system response and to specify the eventual development of additional frequency components. The well-known symmetric Dufrane bearing wear model is used here. The main target here is the investigation of the wear influence on the system response. An experimental layout was constructed for the needs of the current research, including an artificially worn bearing. It was observed that sub- and superharmonics are revealed in the continuous wavelet transform (CWT) of the rotor-bearing system response for worn bearings.
