About the optimal ratio between the main technical parameters of mine electric locomotives

Abstract

The weight of the train in the calculations of mine electric locomotive traction is taken by the lowest value determined from the conditions of the coupling weight of the electric locomotive, heating of traction motors and braking of the train. One of the above conditions in each specific case, depending on the main technical parameters of the electric locomotive and transportation conditions, is limiting and determines the size of the train. In the case under consideration, of the main technical parameters of the electric locomotive, the parameters of the coupling weight, continuous tractive force and continuous speed of the electric locomotive are of decisive importance. It is obvious that a rational ratio between the values of these parameters is of considerable interest, since it makes it possible, other things being equal, to allow a larger train size.
