On the kinematic parameters of the movement of a freight train on various sections of railways

The numerical values of the kinematic parameters of the movement of freight trains and locomotives of electric traction along the route on virtual and real sections of railways of various difficulty are presented, which are given in the form of tabular data and graphical dependencies.Regression equations were obtained to determine the values of the kinematic parameters of the movement of freight trains with a unified mass of the train, including those given, depending on the complexity of the track profile of the studied sections of the railway and locomotives.In this article, to implement the above, the authors use a new method for solving the differential equation of train motion and an algorithm for graphicanalytical calculation of its trajectory for railway sections of varying complexity, based on geometric constructions of changes in the speed and time of train movement along the route, taking into account the specific resultant forces of the train along the route rolling stock and additional graphical constructions on the current integration interval of the average speed movement of the train.The results of the research can be used in the work of specialists of the locomotive complex of the Uzbek railways in assessing the efficiency of using locomotives of the electric locomotive fleet in operating conditions.
