Study on different solutions to reduce the dynamic impacts in transition zones for high-speed rail [PDF]
One of the most important factors influencing the track maintenance is the transitions between parts of the track with different vertical stiffness. The dynamic forces in the super-structure, i.e.

Theoretical Studies on the Longitudinal Inhomogeneity of Track Stiffness and a Track Status Estimation Method [PDF]
Due to material multiplicity, rigid‐flexible hybrid and environmental variations, and so forth, the properties of the tracks will be inevitably changed due to the cyclic loads temporally and spatially. In this paper, a theoretical study is conducted to clarify the influence of the longitudinal inhomogeneity of track stiffness on system responses and ...

A model for the stochastic prediction of track support stiffness [PDF]
As well as guiding the train, one of the key aims of a railway track system is to provide support to the train at the wheel–rail interface that is of near-uniform compliance. Of the various components that make up this compliance, the contribution of the trackbed (ballast and subgrade) is the most difficult to understand and control.

At present, the most common track model is the one in which rails are presented as bars of infinite length rested on continuous elastic foundation. However, some specialists consider the model to be rather ideal for railways in terms of track and the ...

Measuring track vertical stiffness through dynamic monitoring [PDF]
[EN] This paper proposes a methodology for the evaluation of the track condition by means of the measurement of the track stiffness. This magnitude is calculated from vertical acceleration data measured at the axle box of trains during their normal ...
