An analytical model of the rails of ballasted railway track subjected to the dynamic loads are
developed to study forced vertical vibration. In this work, the two rails are modelled as infinite …

The dynamic response of a railway track has been investigated by analytical or numerical
models. When rail supports (sleepers) or foundation contain defects, the damage reduces …

Transition zones in railway tracks are areas with considerable variation of track properties
(ie, foundation stiffness), encountered near structures such as bridges and tunnels. Due to …

The railway track consists of two rails which are solicited the loads from passing trains. Due
to the dynamic nature of these loads, the total forces applied to each rail are unequal and …

Existing analytical models for railway tracks consider only one rail supported by a
continuous foundation or periodic concentrated supports (called the periodically supported …

In a railway track, the sleeper's responses on a non-homogeneous foundation have been
investigated by researchers focusing on the foundation behavior along the rails. However …

The safety of a passing train depends on different factors, of which one of the most important
is the behavior of the foundation. Therefore, the effects of the nonlinearity of ballast on the …

The study of periodic systems under the action of moving loads is of high practical
importance in railway, road, and bridge engineering, among others. Even though plenty of …

In this paper we study the steady state responses of an infinite beam resting on a
tensionless visco-elastic foundation under a harmonic point force moving with a constant …

The dynamical responses of railway track has been carried out by different ways. In this
work, by developing an analytical model for the ballasted railway track which includes two …
