Dynamic Response Analysis of Ballasted Railway Track–Ground System under Train Moving Loads using 3D Finite Element Numerical Modelling

Abstract The faster and heavier trains in modern railway traffic are getting popularity the public transportation authorities of many countries. Such cause higher stresses excessive deformations ballasted track substructure under train dynamic loadings, which raises risk damage derailment. It is thus essential to investigate impact different influencing factors on response track–ground systems. In this study, a sophisticated three-dimensional finite element model simulating realistic moving loads presented used tracks terms stress transmission deflections various train–track–ground conditions. considered study include modulus thicknesses layers, amplitude speed. outcomes encompass important guidance engineers assist finding best possible scheme for design lifetime maintenance.
