Analysis of the resistance to motion in the passenger trains hauled by the locomotive LE 060 EA 5100kW

A New Approach to Use of Traction Power Network in Poland for Charging Electric Vehicles

“…As can be seen in Figure 3, the first part of the mathematical model concerns the journey of a theoretical rail vehicle, the method and methodology of which is widely known and described in detail, among others in [15,[35][36][37][38][39]. Based on input data regarding the type of vehicle and its traction characteristics, understood as the change in tractive force as a function of speed changes F = f(v), and data on the route and the traction power…”

“…As can be seen in Figure 3, the first part of the mathematical model concerns the journey of a theoretical rail vehicle, the method and methodology of which is widely known and described in detail, among others in [15,[35][36][37][38][39]. Based on input data regarding the type of vehicle and its traction characteristics, understood as the change in tractive force as a function of speed changes F = f(v), and data on the route and the traction power network, using the classical equation of motion in accordance with Newton's second law of dynamics, you can receive information about the distance traveled, the power consumption of the vehicle, the load on the power supply system, the vehicle current understood as the current consumed by the vehicle for traction purposes and its own needs, and the charging current of the energy storage tank obtained from braking the vehicle [35,37].…”

“…When carrying out a theoretical journey in accordance with Equation (3), it is necessary to take into account the basic resistance to motion W, which is a representation of the forces that act on the vehicle in motion, and these forces are not generated by the drive system [38,40]. There are three basic types of resistance to movement:…”
