Lightbulb The Influence of Under Sleeper Pads on Railway Track Dynamics
In this work the influence of Under Sleeper Pads on the dynamic forces on a railway track is investigated. A special interest is devoted to the effect of using Under Sleeper Pads in a railway track with changing vertical stiffness. The contact force between wheel and rail and the ballast contact forces are examined. For the investigation a finite element model with the length of thirty sleepers is created and calculations are performed with the software LS-DYNA. Three different cases of varying vertical track
stiffness are studied: the transition from an embankment to a bridge, a randomly varying track stiffness along the railway track and hanging sleepers.
This is one of the innovative Mechanical Engineering Project for Mechanical and Automobile Engineering Student.Complete Report in PDF format is included For study purpose.
