Description:
A railway track system is comprised of several components such as rail, sleeper and ballast. Ballast is the weakest component in the track system and it is subjected to latent dynamic shifting. Constant and continuous loads lead to wear and breaking up of the ballast, thus, diminish the quality of track geometry. This causes unaccounted periodical tamping of track bed. A holistic solution to slow down this process is by installing rubber sleeper pads. Numerical investigation is performed using the general-purpose finite element software ABAQUS for the track system with varying rubber pad thickness and locality. The elastic properties of rubber are expected to lengthen the bending line of the rails and reduce the direct dynamic load on the ballast. Four separate models of the same load, sleeper and rail but with different rubber pad thicknesses is modelled using the finite element software ABAQUS to investigate the effect of the variation of rubber pad thickness in terms of the s...
