Dynamic Behavior Comparisons of Non-ballasted Track Infrastructure of High-speed Railway under Three Different Loads
A three-dimension dynamic finite element model of track -subgrade for a typical non -ballasted track infrastructure of high -speed railway was presented in detail. Using the model, the dynamic behaviour of the high -speed railway infrastructure (including the track and the subgrade) under three kinds of loads ,the wheel/rail force ,the multi-axle load and the single-axle load have been calculated. The comparisons of the dynamic responses were investigated in detail. The results indicate that the wheel/rail force, the multi-axle load and the single-axle load have little influence on the displacement distributions ,but have remarkable effect on the stress distributions.
