Summary

This paper describes how multi-body simulation (MBS) can meet infrastructure needs in various domains. After describing in detail these fields where MBS software may bring improvement in infrastructure design or maintenance, the key-points that have to be taken into account in order to get reliable results, are reviewed.

Amongst different possible fields, the track geometry has been the first one where vehicle simulation was applied. Other purposes are also considered such as evaluating a specific track design, increasing the maximum speed on an existing line, or applications concerning vehicle gauge.

Apart the above applications, new fields where vehicle simulation can help track designers are being investigated such as the influence of short defects on forces generated by the vehicles as well as the relationship between track stiffness and vehicle reactions.

In the last part of the paper the precautions which have to be taken when using vehicle simulation software are described. The validation of vehicle models is a crucial step in the modelling process. This paper gives some key-points for building a reliable model and for using a good representativeness of track geometry in order to obtain consistent and usable results.
