Accounting of random processes when adjusting the overhaul life of machines for reclamation

摘要

Application of procedure modeling a physical process in virtual medium jointly mathematical apparatus allows obtaining forecast parameters of the technical condition. Goal of the study is development of predictive assessment of failure risks for machines with a different overhaul life. Accounting of load characteristics for reclamation machine was explained; development of guidelines on formation of info-analytic basis for the unit machine operation was realized. In particular, the period for maintainability can be distinguished, in this case, the reverse nature of the transition seems to be true that reset the previous operation period and return the value of operating life to initial state. For example, the implementation of the return transition according to the values of moral aging is not possible. Further studies are oriented on development of a methodology for monitoring of variation in the technical condition of a unit machine at a hierarchical level, by combination of risk-failure data for individual parts, assemblies, systems, and for entire system of machine. Electronic diagnostic system for collection of data about a current state of the technical system, combined with a computational model of the intensity of change compared to the basic end values, will allow designing predictive models of failure risks.
