Investigation of the Influences of Track Superstructure Parameters on Ballasted Railway Track Design
The main design criteria of ballasted railway tracks include rail deflections, rail bending stresses, rail wheel contact stresses, sleeper bending moments and ballast sleeper contact pressures. Numerous criteria have been defined for the design of ballasted railway tracks owing to the various mechanical properties of track components and their complex interaction. Therefore, railway track desig...

متن کاملStatic and Dynamic Analysis of Railway Track Sleeper
The increased speed and weight of modern trains puts the components of a railway track in a highly dynamic load situation. Irregularities of the wheels and rails induce substantial dynamic loads that have to be accounted for in the procedure of designing the railway track. The concrete sleeper is an essential part of the track structure and there is a growing demand for improved analytical tool...
متن کاملInvestigating the Behavior of Railway Sleeper for Different Cases and Track Conditions by Using Analytical and Numerical Methods
Railway Sleepers are one of the most important elements in the track superstructure. Their tasks are keeping the track geometry, resisting against vertical and lateral train loads and transferring the train loads to the ballast layers. In this research, the railway sleeper as a beam on the elastic foundation is modeled with finite length. In this regard, two cases including a) beam with constan...
متن کاملA Study to Predict the Development of Wear for the Wheel/interface of a Railway Track
The train transport is often confronted with greatly repeated changes in scope, vehicle travel well-being and transport safety because of the adjustments of wheel and rail profiles. These problems are frustrating and threatening. Thus, there is a requirement for an approach to predicting the wear of wheel/rail to tackle these problems. A new theoretical ground is broken through the build-up a m...
