Evaluating the efficiency of transport operation of an electric tractive rolling – stock on a hilly-mountainous railway section
UDC 629.42:629.4.054, 625.28 BBK 39.232
The article presents the results of validation of operating parameters of 3VL80S mainline (train) three-section electric locomotives on a real hilly and mountainous railway section with non-stop and stop-and-go freight traffic at passing tracks, intermediate stations and intersections as well as estimation of the traction qualities (properties) of the track profile for this section. Criteria for the estimation are the adjusted values of overall and specific power consumption for hauling operation numerically and in terms of money with account taken of the values of equated time of train travel in traction mode and of the specific power consumption per trip. The research results were received using the methods and techniques of the locomotive-traction theory with account of basic indicators of the traction-energy efficiency of 3VL80S use in the form of tabular data and curves. The research results are recommended for practical use by engine-drivers, termotechnic instructors and experts of linear enterprises of the Uzbek railway locomotive complex who deal with issues of energetics of freight and passenger trains movement on the real hilly and mountainous and identical virtual railway sections.
