Fault identification using a structural and functional approach for digitalization conditions

Abstract

One of the fundamental components in equipment maintenance and repair systems that implement modern risk-oriented strategies is information. The effectiveness of taken decisions is determined not only by the volume, but also by the quality of information data. The article formulates and justifies the requirements for the collected information on the technical condition of equipment and data for the analysis of its failures, taking into account modern capabilities and conditions of universal digitalization. The role of mathematical modeling in the formation of data on the functional parameters of the machine is shown, the main stages of construction are outlined and a set of developed mathematical models of the refrigerator is presented. Methods of equipment fault analysis are considered, their characteristics are given, areas and application features are indicated. An algorithm for analyzing events related to the operability of equipment based on entries in the equipment maintenance log is described. The proposed approaches are demonstrated by the example of a refrigerator with walking beams and a hydraulic drive, which is an integral part of the technological line of the CCM and has the most characteristic features of metallurgical equipment, which allows to use the solution of the problem of collecting and processing information about the technical condition of the CCM refrigerator as a standard.
