The Influence of Subgrade Subsidence on Train Track Dynamic Interaction (2012)

Abstract This paper reports results from a numerical model to calculate subgrade settlementin railway tracks due to repeated dynamic loading. The trains are modelled as rigidbody 2-axle carriages on two layers of springs. The track is modelled as a beamsupported on three layers of springs. Permanent deformation of the subgrade layer iscalculated on the basis of a power law assumption. Patterns of dynamic forces arecalculated on a smooth track and on a track subject to an initial subgrade ‘pothole’.The latter is shown to grow with repeated loading and to change the mean patternsof applied force.
