С целью выбора алгоритма управления локомотивом, при прогнозировании рационального режима движения поезда в эксплуатации методами математического моделирования, выполнен расчет основных технико-экономических характеристик работы тепловоза 2ТЭ116У с составом, при использовании полной мощности и при управлении по параметрам режимной карты. Основой метода является динамическая модель движения поезда на участке железной дороги с заданным профилем. Для верификации разработанного метода численные исследования выполнялись в широком диапазоне изменения весов составов, не превышающих расчетный вес. Выполнено сравнение полученных результатов со статистическими данными о значениях эксплуатационных характеристик движения поездов на сети железных дорог России. Показано, что моделирование режимов движения поезда при использовании полной мощности локомотива дает значительную ошибку при расчете технической скорости, весовой норме поезда и расхода топлива и не позволяет рассчитать рациональный алгоритм управления локомотивом по используемым критериям оптимизации с учетом условий эксплуатации. Обоснована необходимость при выборе рационального алгоритма управления локомотивом учитывать реальные условия эксплуатации движения поездов по пакетному или частично пакетному графику, которые отражены в параметрах режимной карты.

In order to choose locomotive control algorithm when prognosing train motion rational mode in an exploitation by the methods of mathematical modeling, the calculation was performed of main technical and economic characteristics of the operation of diesel locomotive 2TE116U with a stock at the use of full power and at control, basing on the parameters of a mode map. The method basis represents train motion dynamic model on a railway section with a given profile. To verify the developed method, numerical studies were carried out in the wide range of changes of stock weights which not exceed the calculated weight. The obtained results have been compared with statistical data on the values of operational characteristics of train motion on Russia railways. It has been shown that train motion mode modelling at the use of locomotive full power gives a significant error at calculating technical speed, at the norm of train weight rate and fuel consumption and does not allow calculating locomotive control rational algorithm on optimization used criteria inclusive of operation conditions. At the choice of locomotive control rational algorithm, the necessity is substantiated for taking into account real conditions of train motion operation by batch or partially batch schedule which are reflected in mode map parameters.
