| 英文摘要 | Conventional vibration signals processing techniques are most suitable for stationary processes. however, most mechanical faults in machinery reveal themselves through transient events in vibration signals. that is, the vibration generated by industrial machines always contains nonlinear and nonstationary signals. it is expected that a desired time-frequency analysis method should have good computation efficiency, and have good resolution in both time domain and frequency domain. in this paper, the auto-regressive model based pseudo-wigner-ville distribution for an integrated time-frequency signature extraction of the machine vibration is designed, the method offers the advantage of good localization of the vibration signal energy in the time-frequency domain. kernel principal component analysis (kpca) is used for the redundancy reduction and feature extraction in the time-frequency domain, and the self-organizing map (som) was employed to identify the faults of the rotating machinery. experimental results show that the proposed method is very effective. |
