Train energy map
It is presented the calculation of the energy state of the train through the potential and kinetic energy, which is spent on overcoming the forces of the main and additional resistance to the train movement of the train. The contours of the train energy state clearly demonstrate the change in the train energy, which makes it possible to determine the modes of the train movement based on the energy approach. The proposed calculation method is especially relevant when determining the operating modes of energy storage units on traction rolling stock.
