  • A Review of Feature Extraction Methods in Vibration

    2020-7-2 · It is more difficult and complicated to analyse the condition of slew bearings that operate at a very low speed than to analyse that of typical rolling element bearings. Slew bearing signal has a low energy. It is non-stationary, chaotic and practically hard to analyse. Due to its low energy, the signal is masked by a higher background noise level.

  • Vibration and acoustic emission-based condition

    2012-8-3 · The use of vibration data from slow-speed slew-bearings has been notoriously unsuccessful in predicting bearing failure. There are a number of reasons for this. Primarily, the very slow speeds involved (1 - 4 rpm) lead to very low rotational energy release. The operation of a slew bearing is often intermittent and non-cyclic.
