Kyslyi D. Increasing the energy efficiency freight trains conducting by diesel locomotives

Dissertation is devoted to the operating reduce train traction expenses by choosing economically justified conduct of the individual regimes. In this paper, using a mathematical simulation model trains, solved the problem of the definition of rational management locomotive for the individual phases of motion and compiled relevant functional dependencies. rational management energy-saving functions allow you to calculate the trajectory of train movement, excluding the timetable. Also, using the method of local variations, equation of train movement is solved in a dependency ratio of fuel consumption - the time of train movement, which allows to take into account the schedule of trains. For the possibility of using method of definition the individual modes of rational conduct in onboard systems the hardware has been developed to process locomotive parameters. The results of the comparison of traction calculations performed by the calculation algorithms of individual rational regimes of traction calculations made by other methods and the actual travel data indicate that the efficiency of the algorithms discussed in amounts of 2-12%.
