The Study On Train Operation Simulation System Based On Dynamic Model

Using its advantages of high running speed, better transport capacity, being little effected by the natural environment, steadiness and safety, rail transport plays an important role in the development of the national economy. In the existing conditions of train line section, how to further improve the railway transportation volume under the premise of ensuring the safety of train operation and how to further improve the transport efficiency have become an important issue.Before solving this issue, first the external force of the train in various operating conditions should be analyzed. Generally speaking, the external forces of the train are traction, running resistance, braking operation, self-gravity and the support force provided by the line. This paper briefly introduces the conformation cause and calculation methods of these external force, and the impact on the train. After these researches, the dynamic model of the train will form. Using the computer simulation technology, the dynamic simulation system is established. The system will simulate the line segment and the operating environment.Simulation language uses VC++ 6.0. Through the efficient code and friendly development environment, and the strong MFC class library provided by the VC++6.0, the simulation process of the train dynamic model become easier. The simulation system complies with the actual operation of the train. Finally by comparing the simulation results with real results, analyzing the data, the paper certifies the correctness and the reliability of the simulation system.
