And based on Visual Basic 2008,a traction simulation platform of urban mass transit vehicles is designed and developed. Through simulating urban mass transit vehicles operation, and providing computer simulation of urban mass transit vehicles, running track, train load,and control strategy of train operation,the parameters such as the velocity of urban mass transit vehicles operation, traction power cost and traction motor current,etc would be gained. And based on the simulation results, a series of curves would be drawn and the report forms can be automatically generated. And then these data.after they are functionally processed,might satisfy different demands. The calculations of the test lines indicate that this system is simple and easy to use,its results are accurate, and it has some practical value.
