The research is based on the data obtained by an on-board monitoring system COMPACS®-EXPRESS-3 and aimed mostly at increasing reliability of machinery diagnostics of rolling stock units (in electric trains) by finding codependences in changes of vibration diagnostic features during condition degradation process from analyzing statistic properties of their distribution.
At the same time, the results obtained during the course of work are invariant to the diagnostic subject and can apply to machinery in hazardous production facilities in FEC.
The completed research allowed to establish the criteria according to which the cases of defect development were found using trends of vibration diagnostic features.
