Discrete Controlled Train Traction Calculation Model

In order to solute train traction calculation problem based on discrete control, the paper builds up a general train traction calculation model. The model includes multi-particle train model and three main operation processes. The processes are train start and acceleration process, adjustment velocity process and stop process. In train start process, traction force is adhesion tractive effort or max current effort. In brake process, brake force is calculated by cars' actual brake-shoes pressure and their friction factors. In brake to stop process, the resistance brake on locomotive is inoperative. The paper chose train's balancing speed as target speed on each railway section and to shift control gears. Energy consumption is deduced by reducing unnecessary brake process. According to these analyses, the train traction calculation program is developed. Tests indicate that the model is effective and reasonable.
