The state of mine electric locomotive transport and the main directions of mine electric locomotive drive improvement are shown. The expediency of introducing a new train weight limitation into the traction calculation methodology under the condition of electric locomotive drive acceleration is indicated. The criterion for electric locomotive drive control when moving the assembled train from the place is given, the implementation of which allows to increase the service life of trolleys coupling devices. The possibility of increasing traction properties of mine electric locomotives by means of combined drive is considered. The efficiency of using of traction motors with mixed excitation on mine electric locomotives is shown.
The article presents a methodology for determining the main static parameters of a combined drive of a mine electric locomotive, which is a combination of a traditional propulsion system and an additional traction linear electric motor. Since the thrust force of the additional propulsor does not depend on the conditions of traction of the electric locomotive wheels with the rails, the use of such a system will increase the train mass with the electric locomotive coupling mass remaining unchanged. The basic ratios and algorithm of determining the additional propulsion power at different ways of electric motor control and different technological parameters of electric locomotive transport are given. A block diagram and a description of the algorithm for calculating static parameters of the combined drive of a mine electric locomotive for different conditions, based on limiting the traction force of the main drive by a long-term value is given.
