Unsupported sleepers or void zones in ballasted tracks are one of the most recent and
frequent track failures. The void failures have the property of intensive development that …

The ballasted track superstructure is characterized by a relative quick deterioration of track
geometry due to ballast settlements and the accumulation of sleeper voids. The track zones …

It is generally considered that a Timoshenko beam is superior to an Euler-Bernoulli beam for
determining the dynamic response of beams at higher frequencies but that they are …

A singular rail or wheel surface irregularity, such as a squat, insulation joint or wheel flat, can
cause large wheel-rail impact force. Both the magnitude and frequency content of the impact …

The dynamic properties of a railway track are important for both the generation of rolling
noise and the development of rail corrugation. A conventional track consists of long rails …

The ability to assess the risks of the functional safety of railway tracks allows harmonizing
characteristics of track elements under certain operating conditions under certain …

Intelligent data-driven monitoring procedures hold enormous potential for ensuring safe
operation and optimal management of railway infrastructure in the face of increasing …

Rail pads are important components in railway tracks that greatly influence the vehicle-track
interactions. A vehicle-track vertically coupled dynamics model that considers the distributed …

To investigate the properties of elastic waves propagating in the periodic ballasted track, a
double-rail phononic crystal (DRPC) model which consists of two parallel rails fastened on …

Ballast bed exhibit the characteristics of granular material that present challenges in
modelling its broadband vibration. A refined discrete element model of ballast bed corrected …
