The Research On Simulation System Of EMU Traction Calculation

Simulation system of train traction calculation is organic integration of traction calculation, train operational analysis, and train computer programming strategy to realize the simulation of train operation.Nowadays, the research on train traction calculation is often used in urban track traffic area, but not in high-speed EMU. Therefore research results are few which can meet the requirement of operation unit. This system, as one of simulation modules in EMU driver train system, choosing CRH2 as the simulation example, builds a simulation platform of traction simulation to meet the requirement of train traffic department. The simulation results of calculation show that there is usual traction Time interval curves and Speed Interval curves, and the whole process can meet the requirement of line condition and vehicle operation.The paper based on the research status at home and abroad, according to the based theory of train traction calculation, analyzes the calculation character of longitudinal force such as traction force, running resistance, brake resistance, and the influence to railway train. The paper analyzes the familiar simulation model of train traction calculation, explores the theory of real-time simulation of train traction and the problems of the calculation of breaking point. Moreover the paper raises the solution to the problems. The paper research on gross structure of train simulation system, uses the C language as programming environment and the software of AutoCAD as drawing utilities to draw the calculation result of calculation. The paper state the design of every module in the system. Finally the simulation system using the track data of the line from Wuchang to Changsha, according the calculation, get the data and analyze the result. The result shows that the system runs stably and the calculation is reliable. The result is verified by the theory of railway train, realizes the intended design goal.
