Abstract:
The paper presents results obtained from experimental and simulation tests of trains, treated as simplified one-dimensional models of railway vehicles. This approach to train dynamics enables to assess train forces and their impact on dynamic characteristics, for example related to some problems of rapid starting or emergency braking. These works were used to implement them as a solver mechanism in the simulator of catenary maintenance trains, whose features in the article are discussed. In the paper algorithm of operating vehicles by their drivers in different driving scenarios are presents. The algorithm described simulator must meet atypical requirements resulting from the specific properties of the simulated vehicles.The paper describes also the methodology of identifying driving system of modeled vehicles and the way of adaptation of parameters obtained experimentally. Then, in brief, issues related to the image animation and presentation in the simulator are discussed. Also the most important rules of operating rail vehicle simulator, selecting proper scenarios and using effective training methods are characterised. Results of operational and numerical tests presented in the paper reflect in details processes accompanying the operation of catenary maintenance trains. The experimental test methodology to the real railway vehicles to acquire some missing work parameters was allowed. Results of the presented research indicate a large convergence of theoretical results with the experiment.The obtained result allowed to validate the work of the simulator

Abstract:
Due to the fact that training simulators of railway vehicles must fulfill unique requirements resulting from the specific properties of the simulated vehicles, in this article on determining the main criteria for modeling the dynamics of such systems was presented. A methodology used in the study on the selection of parameters of the modeled vehicle and its driveline based on experimental studies was described. Adaptation of parameters obtained from the experimentally test into the dynamics model of vehicle was presented. Currently used solutions in simulators as well as issues related to animation and presentation of the image was provided. The requirements for the operation of the rail vehicle simulator, as well the design requirements for visualization of the image were defined and discussed.
