railway track stiffness variations – consequences and countermeasures
the track stiffness experienced by a train will vary along the track. sometimes the stiffness variation may be very large within a short distance. one example is when an unsupported sleeper is hanging in the rail. track stiffness is then, locally at that sleeper, very low. at insulated joints the bending stiffness of the rail has a discontinuity implying a discontinuity also of the track stiffn...

متن کاملInfluences 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 کاملOverview and Outlook
When you do some mountaineering...you sometimes...want to climb to some peak but there is fog everywhere...you have your map or some other indication where you probably have to go and still you are completely lost in the fog. Then...all of a sudden you see quite vaguely in the fog, just a few minute things from which you say, “Oh, this is the rock I want.” In the very moment that you have seen ...
