Research And Calculation On Rail Transit Line Braking Traction Control System

This paper is organic integration of traction calculation, train operational analysis, and train computer programming strategy to realize the simulation of train operation.In the area of urban rail transit design, urban rail transit traction calculation can provide guidance on optimal design of line plane section and line longitudinal section by the Line Design major, selection of vehicle technical parameters by the Vehicle major, design of block section by the Sign major, determination of the main substation scale and substation number and distribution by the Traction Power Supply major, the ventilation planning of underground station and subway tunnel by the Environmental Control major, and etc. Therefore, it is the effective way of solving the existing city traffic problem to develop urban mass transit.This paper describes the calculation method of dynamic parameters in urban rail movement process, and try to build a dynamic mathematical model of the train, based on the train traction calculation theory, then uses the C++ language as programming environment to calculate the results of the train traction. Finally, the simulation results has reference value to exert the traction ability of vehicles, arrange vehicle's schedule and economize energy.
