A Concept to Estimate the Life Cycle of the Railway Track Using Finite Element Modeling

Abstract

When a train is running on a railway track, its wheel-rail's dynamic and static forces exerts a vertical, longitudinal, and lateral load on the ground. A railroad track has two main parts which are superstructure which includes fastening systems, tie, and rail and substructure which includes fill material, bottom ballast, top ballast, subgrade, and sub ballast. Rail tracks that are ballasted get deformed with time in both lateral and vertical directions that lead to, in case of persistent traffic loading, deviations from the intended geometry.This study will develop a simulation of a complicated three-dimensional finite element model so that the ballast can detect the railway's life cycle. The simulation is created so that the railway track's cycle can be determined.
