Dynamic train/track interaction including model for track settlement evolvement
2004 (English)In: Vehicle System Dynamics, ISSN 0042-3114, Vol. 41 (Supplement), 667-676 p.Article in journal (Other academic) Published
A ballasted railway track exposed to train traffic will degenerate. Track alignment and track level will deteriorate. Settlements of the track (loss of track level and alignment) require maintenance; the track is lifted and aligned, and new ballast material is injected under the sleepers. This paper presents a computer model by which the dynamic train/track interaction can be simulated and the permanent deformation of the track (i.e. track settlements) can be calculated. The voided sleepers ("hanging" sleepers) phenomenon will also be discussed.
