Abstract
This article presents the results of research in the area of a universal vibrodiagnostic criterion search suitable for assessing the dragline generator groups’ actual state degradation degree. This search was carried out on the vibration parameters’ comprehensive analysis basis and common diagnostic criteria use suitable for the development of complex mechanical systems state change mathematical degradation models. The analysis of the diagnostic data obtained on dragline working power-mechanical equipment allowed to classify this type equipment defects into the basic groups, to which in the aggregate correspond more than one hundred and twenty diagnostic features in the analysis of vibration parameters. In addition, these signs were formalized to ease their use when developing the complex systems automated control algorithm code based on the generated mechanical vibration parameters. The developed set of diagnostic rules for detecting defects based on the analysis of mechanical vibration parameters and the unified diagnostic criteria for estimating the state based on the mechanical vibrations parameters analysis can act as a basic platform for the implementation of the maintenance system elements according to its actual technical condition. In this article it is convincingly proved that only with the wide use of vibration diagnostics modern methods and non-destructive testing we get the opportunity for mining machines’ equipment timely defect detection and development of predictive models for their technical condition change. The scientific results obtained within the frames of the present work categorically prove the principled consistency of the new criterion being developed for assessing the dragline generator groups actual state degradation degree based on a proposed unified diagnostic criteria group complex realizing principle. The application of the new criterion in practice will improve the forecast efficiency of mine draglines’ converter units and small generator groups diagnostic parameters changing process.
