Оцінка факторів, що визначають термін ефективного утримання локомотивів

Abstract

UA: У статті розглядаються питання оцінки факторів, що впливають на термін утримання локомотивів за умови їх ефективного використання. У зв’язку з фізичним та моральним зношуванням рухомого складу у сучасних умовах найважливішим напрямком забезпечення його ефективної роботи є оптимальне поєднання стратегії подовження строку служби та заміни на новий ресурс рухомого складу.

EN: It is shown that in today's aging locomotives and locomotive repair facilities sector a situation which is critical for the industry. This results in the formation of new approaches to system maintenance locomotives, which will be targeted at the factory, in which functions will include monitoring the mechanical condition and upgrade the park operated. In these circumstances, an important choice stanovytsya technical operation of locomotives. Based on changes in the cost modeling for various lifetime by the developed program on the computer were obtained are given the cost of maintaining locomotives. For the considered case received, after 1817 year of operation traction rolling stock begins to operate inefficiently. However, it should be emphasized that the idealization adopted stable, not rising costs of maintenance, repair, overhaul and fuel and lubricants eventually somewhat negate the operation of the real dynamics of changes in estimates of effective life. However, it can be noted local minimum unit costs of locomotives with factory price 5·106 UAH in the area 1211 years of operation, due to the major overhaul of the KR-2.
