Influences of Railway Track Geometry Parameters on Ground-Borne Vibration
One of the most important challenges in the development of urban railways network is the effects of railway vibrations on human and adjacent structures. Although various investigations into the sources of railway vibrations have been conducted, very few research works have been reported on the influences of track geometry parameters on the level of vibrations. This is addressed in this resea...
متن کاملInvestigation 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 کاملA Study of Track and Train Dynamic Behavior of Transition Zone Between Concrete Slab Track and Ballasted Track
When a train is traveling along the transition such as slab and ballasted track, dynamic behaviors of rail system and train are abruptly changed. In R&D project, the newly-developed precast slab track system and track transition between slab and ballasted track was planned to construct in 2006 on the newly-built Jeolla-line. Maintenance demand, settlement and component degradation were predicte...

متن کاملEffects of track characteristics on dynamic responses of train-bridge systems
High speed trains are an indispensable part of rapid transportation systems in many countries. As the fastest means of transport on the ground, these trains are extremely sensitive to the terrain and track conditions. Geometrical irregularities and mechanical characteristics of the track, together with inconsistencies in the lane (including bridges that support the track) are considered importa...
