- •
Periodically correlated random processes methods are used for mechanical system fault identification and classification.
- •
Mathematical model of vibration signals on the basis of harmonic series representation is used for early diagnostics.
- •
Faults detection examples are given for rolling/sliding bearings and gear boxes.
