The Train Operation Control Simulation and Implementation of Train Driving Simulation System

With the accelerated development of railway, we not only pay more attention to its running safety, but also the effect of driving simulation system on driver training is growing. Traditional driving simulation system lacks of accurate dynamics model. So it is difficult to meet the needs of railway development. This paper is based on the improved multiple particle dynamics model, constructing train dynamics model to control the running of the train and using improvement of mixed operation control strategy in order to meet the demand of the engineering analysis and optimize the train operation. Through the analysis of different train control strategy and establishing train HX_3DB entity simulation model, the train operation control strategy of the multiple particle dynamics model is analyzed and verified,the results show that the entity train running speed is steady, no obvious velocity jump. By using improvement of mixed operation control strategy energy saving effect and economic applicability are good . system meet the requirements of railway training and engineering analysis.
