Train/track interaction model

Consulting

The aging of the various components of the train track is a major concern for maintenance. Experience with high speed trains indicates that train/track interactions need to be taken into account to study these effects properly.

SNCF (French Rail Road Company) needed a simplified coupled model (track and vehicule) to answer questions such as

• When is it important to take into account track dynamics for the evolution of geometrical defects?
• What is the impact of each layer component on the global track behaviour?
• What is the influence of non linearities?
• What is the influence of layers variability?

Special effort has been made to develop specific interfaces : Matlab GUI (graphical user interface) and parameters handling in Excel with ActiveX commands.
