TrainDy, a new UIC simulator for the longitudinal dynamics of trains

摘要

In order to increase the productivity of freight trains and to harmonize the standards of different countries, there is the need for a new and reliable numerical simulator, since the in-line test campaigns are expensive and they should be reduced to a minimum amount. Furthermore, this simulator should easily be customized by each Railway Operator. In order to face these challenges, the UIC decided to improve and to validate the software TrainDy, and to deliver its source code to railway Operators, Research Centres and Universities that will join an ad hoc Consortium, led by the UIC. This paper gives the outlines of the numerical models implemented in TrainDy and shows some of the results of the validation process undertaken.
