The work is devoted to the relevant issue of choosing a technical operation strategy for modernized shunting locomotives. To achieve this goal, the existing indicators evaluating the technical operation components were considered and a new evaluation criterion was proposed.methodology. Applying a comprehensive approach to assessing the technical operation effectiveness, a new indi cator, a complex technical operation coefficient, was developed. A mathematical model for determining the complex technical operation coefficient was developed.findings. The modeling of the change in the scope of unplanned repairs based on the existing requirements to the value of the percentage of faulty diesel locomotive locomotives. The complex technical exploitation coefficient for different strategies of scheduled technical maintenance and repairs is calculated.originality. Dependences are obtained for unplanned repairs depending on the percentage of faulty locomotives in and the number of sections at the disposal of the locomotive depot. A new criterion of estimation of systems of technical operation of locomotives is proposed and efficiency of its application is proved.Practical value. Modeling was carried out for two types of work (shunting and removal) and four maintenance and repair systems. Calculations of the complex technical operation coefficient for modernized shunting locomotives of the ЧМЕ3М series showed that the change in its value is 3.7-4.25 UAH/kWh. Thus, it is preferable to apply the fourth strategy from the considered maintenance and repair strategies. Due to its application, a rational technical operation system for modernized shunting locomotives of the ЧМЕ3М series with diesel engines Cat 3508 was choosen.
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.
