Models are used by the simulation system and the models comprise a traction system model, a braking system model, a basic resistance system model, a line system model and a kinematic physical model. Thorough analysis is conducted on internal and external elements that influence a train motion state through the models, results simulated by the traction system simulation module, the braking system simulation module, the kinematic physical simulation module, the basic resistance system simulation module, the line system simulation module and the kinematic physical simulation module according to corresponding simulation models are closer to actual train states and requirements of engineering application. In addition, a train controller model and a corresponding train controller simulation module are added to the train motion simulation system, analogue simulation of controlling of a controller to a train is achieved so that analogue simulation of the train motion simulation system to train operating is closer to actual train states, more intelligent and closer to the requirements of engineering application.

Description

technical field [0001] The invention relates to the technical field of urban rail trains, in particular to a train motion simulation system. Background technique [0002] In recent years, with the support of the development of wireless communication technology and security computer technology, the urban rail signaling system has developed towards a more comprehensive, efficient and automated direction. In order to ensure the development and improvement of the urban rail signaling system, a pure software that can run on a general-purpose computer, and a train operation and control model whose accuracy and performance can approach the practical level is not only the foundation but also the driving force. It enables ATS, ATO, The function development of subsystems such as ATP is faster and more convenient. [0003] The operating environment of urban rail trains is quite complex, and the stress on the train during operation is as follows: figure 1 As shown, in addition to bein...

Problems solved by technology

[0005] In view of this, the present invention provides a train motion simulation system to solve the problem that the model used in the existing simulation system is simple, only from the traction force of the train motor and the frictional braking force of the skid, and not from the internal factors of the train. Considering the motion characteristics of trains from different angles, it cannot meet the requirements of engineering applications
