Influence of temperature gradient of slab track on the dynamic responses of the train-CRTS III slab track on subgrade nonlinear coupled system [PDF]
Scientific Reports, 2022 Temperature is an important load for ballastless track. However, there is little research on the system dynamic responses when a train travels on a ballastless track under the temperature gradient of ballastless track.

A STUDY ON THE WHEELSET/SLAB TRACK VERTICAL INTERACTION [PDF]
Fiabilitate şi Durabilitate, 2012 This paper deals with the interaction between a moving wheelset and a slab track due to the short-pitch corrugated rail. The wheelset is modeled using a free-free Timoshenko beam with attached rigid bodies as the axle boxes, wheels and brake discs.

Modelling of Floating-Slab Track with Discontinuous Slab [PDF]
Journal of Low Frequency Noise, Vibration and Active Control, 2006 A floating-slab track with discontinuous slab provides a spatially-varying stiffness under a constant moving load. When a train moves on such a track, even with the absence of rail roughness, a parametric excitation develops as wheels move up and down applying dynamic forces at the wheel-rail interface.

Influences of cement asphalt emulsified mortar construction on track slab geometry status [PDF]
Railway Sciences, 2023 Purpose – The construction of cement asphalt (CA) emulsified mortar can obviously disturb the slab status after the fine adjustment. To decrease or eliminate the influence of CA mortar grouting on track slab geometry status, the effects of grouting ...
