Fully three-dimensional analysis of high-speed traintracksoil-structure dynamic interaction [PDF]

open access: yes, 2010
In this paper, a general and fully three dimensional multi-body-finite element-boundary element model, formulated in the time domain to predict vibrations due to train passage at the vehicle, the track and the free field, is presented.

Incompatible thermal deformation of interlayers and corresponding damage mechanism of high-speed railway track structure

open access: yesHigh-Speed Railway, 2023
In the service period, the instability of ballastless track bed are mostly related to the damage of interlayers which are mainly resulted from the incompatible thermal deformation of interlayers.

Railway superstructure for high-speed rails [PDF]

open access: yes, 2021
The construction of the track is solved as a conventional (with track ballast) or as a ballastless track (without track ballast). When deciding on the choice of the most suitable track design for high-speed rail, it is necessary to emphasize that with ...

Transverse Oscillation of a Base Slab Section of Ballastless Track

open access: yesWorld of Transport and Transportation, 2019
The study is devoted to construction of a mathematical model of a slab of a ballastless base of a railway track, assembled from separate segments fastened together. Each rectangular segment is modeled by a transversely isotropic prestressed plate. An equation has been obtained that allows researchers to study the natural oscillation frequencies of a ...
