Methodology for analyzing reliability of the equipment of electric locomotives 2ES10

Abstract

The article deals with the analysis of reliability of the equipment of 2ES10 electric locomotives with asynchronous traction motors as a complex system and equipment failures that are often encountered during operation. All submitted failures are divided by type of equipment. Based on the Pareto analysis, the main limiting units of these electric locomotives with the lowest reliability are determined. Based on the Pareto analysis, the frequently failing elements of the main limiting components are determined, which are the mechanical part, wheel pairs, brake equipment, traction drive and traction motors. These elements have a major impact on the safety of train traffic and therefore it is extremely important to constantly assess the condition of these elements. Attention is focused on the analysis of risks associated with the possible formation of operational failures, the system of planned preventive maintenance, methods and tools for assessing reliability, incorrect regulatory and documentation support and fixing operational defects, and their subsequent processing. Such a study makes it possible to improve the safety of the transportation process by careful monitoring of the most vulnerable areas of the rolling stock. This reveals the prefailure state before it occurs. The results of the study can be used as a basis for adjusting the current structure of the repair cycle in terms of reducing inter-repair runs.
