Traction Research And Development Of The Computer Simulation System

Traction calculation of the design of rail transportation has a very important role, it is line level, Profile Optimization Design, choose rolling stock technical parameters, to determine the main lines of the traction substation step-down the size and number and distribution of the important basis. The train traction calculation and simulation for, and the traction calculation results back to the planning, design, operation and going to improve the economic efficiency of rail transport system.There are a lot of traction calculation software, although functional, but most deep enough, the lack of electric drive system design requires a description of the calculation parameters, such as the motor equivalent current, the equivalent DC current, traction power, electric braking power, etc.. At the same time most of the calculation of a simple strategy of rapid traction and can not close the driver's driving habits, the simulation accuracy is not high.Based on the principle of the railway train traction calculation, the calculation of rail traction. Including the train by the traction, resistance, braking, traction running, coasting running, brake running state, run equation, the operational strategy and traction energy consumption calculations.Based on the study train traction calculation software, based on the simulation of different needs, build a strategy based on different traction traction model, including rapid traction, traction and optimal traction model of the economy. In this paper, MATLAB software simulation system developed traction calculation, developed an advanced, set of freight trains, passenger trains, EMUs, urban rail train in one, including the traction calculation function and operation of the train traction calculation simulation software completed, including needs analysis, functional design, modules, interface design, database design and commissioning and a series of work.Finally, computational simulation of the traction systems, traction on the Cairo subway was calculated results show that the advanced performance of the system to good effect...
