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 …

Transition zones in railway tracks are the locations with considerable changes in supporting
structures. Because of the difference in the structures or material properties, the differential …

The deterioration of the sleeper support on the ballasted track begins with the accumulation
of sleeper voids. The increased dynamic loading in the voided zone and the ballast contact …

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 …

In this study, a wheel-rail transient rolling contact model capable of accounting for the
nonlinear displacement-force properties of hanging sleepers is proposed. The sleeper …

With development of the heavy-haul railway, the increased axle load and traction weight
bring a significant challenge for the service performance and safety maintenance of the …

Nowadays, with various advancements in the railway industry and increasing speed of
trains, the design of railway tracks and vehicles has become vitally important. One of the …

The support condition of railway sleepers has a significant effect on the mechanical behavior
of railway tracks due to the passing of different trains. One of the important issues in this …

Increasing the axle load causes track deterioration and permanent settlement of the ballast
layer. In the ballasted railway tracks, due to the inevitability of unequal settlements in the …

The article presents a methodic for analytical determining forces, displacements, modes and
frequencies of natural flexural vibrations of a beam on elastic foundation. The beam consists …
