The article presents the mechanism of unit vibration trends, which represent the mixture of gradual and discontinuous processes, and the mechanism of spreading of vibration spectrum in case of the unit degradation.
We proposed and tested the method of recursive synthesis of orthogonal diagnostic features that is invariant to the unit type. This method based on the blocks of spectral matrix realizes the concept of "collective recognition". In addition, we developed and tested deterministic models of unit performability and method of approximation of multimodal intensity of wear by Veibull-Gnedenko mixture of distributions.
The results obtained form the basis of the strategy for minimal cost diagnostics and enable significant reduction of costs and shortening of the period of implementation of the systems for condition monitoring of hazardous production facilities.
