The article focuses on monitoring of wheelset binding bands condition of electric locomotives with rotary-field traction motors and, since it is a very important factor in reliability of the electric locomotive by and large, the obtained decisions are based on its results. In analysis there were examined wheelset defects of common occurrence and their natural wear during exploitation. The electric rolling stock works under complicated conditions which affect the nature of wear and electric and mechanical equipment damage. One of the main tasks is to ensure reliable operation of different machinery, as failures on track disorder the traffic schedule, distort the transportation rhythm, leading to considerable loss of throughput capacity of sections, which also reduces movement safety and results in great economic losses. Reliability evaluation is a set of measures aimed at monitoring of condition of electric locomotives, which is based on real operational particulars. By virtue of these particulars one can see an ultimately complete picture, analyze it and correct the structure of repair cycle of electric locomotive particulars. The article accentuates the analysis of risks, related to probable defects, unexpectedly high wear out, incorrect choice of repair cycle structure, ways and tools of reliability evaluation, incorrect statutory, results of incorrect measurement.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
