Prediction of Dynamic Train-Track Interaction and Subsequent Material Deterioration in the Presence of Insulated Rail Joints

Numerical analysis of high-frequency dynamic train-track interaction is combined with the analysis of material deterioration in terms of rolling contact fatigue (RCF) and plastic deformation to analyze the influence of insulated rail joints. These joints form local rail irregularities and lead to a local change of dynamic track stiffness. Dynamic responses at wheel passes are evaluated. Further, related plastic deformations at the joint and increased RCF impact along a stretch of the track adjacent to the joint are predicted.
