Paper Title:
Finite Element Analysis of Ballastless Track Rail-Floating Slab’s Dynamic Characteristics
  Abstract

By using the finite element analysis software ANSYS, a three-dimensional dynamic finite element model of ballastless track rail –floating slab was established. The model takes into account of the track irregularity case, the analysis the dynamic response characteristics of the rail and floating slab under the vertical force in the track structure. The results showed that: when the train load goes through the line, the dynamic response of the rails and floating slabs gradually increases to maximum and then decreases; the maximum response displacement of rail is at 0.625mm ~ 0.75mm and the maximum response acceleration values is in between 5000m/s2~6000 m/s2; the maximum response displacement value of floating slab is about 0.25mm, the maximum response acceleration value is between 0.8 m/s2~1.2m/s2.
