Енергооптимальні рішення при експлуатації механічної частини локомотивів / Микола Баб’як, Любомир Вархоляк, Роман Шидловський // Енергооптимальні технології, логістика та безпека на транспорті : матеріали 3-ї Міжнародної науково-практичної конференції, 9-10 листопада 2023 року. — Львів : Видавництво Львівської політехніки, 2023. — С. 49–51.978-966-941-868-5https://ena.lpnu.ua/handle/ntb/61701The issue of increasing the reliability of operation of electric locomotives of mainline and industrial railway transport, in particular the elements of the mechanical part, is considered. The design of the nodes supporting the locomotive body on the bogie frame should ensure good dynamic qualities of the locomotive, which allows operation at a higher speed, while the traction characteristics of the locomotive and safety of movement should be ensured. The relevance of this work is emphasized by the increase in the volume of freight transportation and the use of electric freight locomotives in passenger transportation, which significantly affects both the rail track and the wear of individual elements of the mechanical part that interact with each other. This is especially true for friction assemblies, side supports, and cradle suspension. A comparative analysis of the work of cradle suspension units of different locomotives was carried out. The main factors affecting the increased wear of individual elements of the mechanical part, including the cradle suspension, have been established. The existing and prospective elements of body support nodes are analyzed. Recommendations are given for increasing the operational reliability of the mechanical part of electric locomotives.49-51ukЕнергооптимальні рішення при експлуатації механічної частини локомотивівArticle© Національний університет “Львівська політехніка”, 20233Bab’iak M.
