FINITE ELEMENT TRACK BUCKLING MODEL

This paper stimulates track stability so that the buckling load of the track can be predicted. Thus, the criteria for track design, maintenance, and evaluation can be formulated. The simulation is achieved by a finite element model. Only the basic applications and potential of the model are illustrated. The model is in reasonably good agreement with test data in the literature. A parameter investigation indicates that the lateral thermal buckling load of a tangent track is significantly affected by changes in lateral ballast resistance, misalignments, and the presence of ineffective ties.
