Experimental study of the gap between track slab and cement asphalt mortar layer in CRTS I slab track [PDF]

open access: yesJournal of Modern Transportation, 2018
Gap exists in the interface of cement asphalt emulsion mortar and CRTS I track slab universally, which is more severe at four corners than other parts of the track slab.

A STUDY ON THE WHEELSET/SLAB TRACK VERTICAL INTERACTION [PDF]

open access: yesFiabilitate 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]

open access: yesJournal of Low Frequency Noise, Vibration and Active Control, 2006
This paper presents three different methods for modelling a track with discontinuous slab under oscillating moving loads. These are the Fourier-Repeating-unit method, the Periodic-Fourier method and the Modified-phase method. The first two methods, borrowed from the literature of periodic infinite structures, are accurate if careful consideration is ...

Influences of cement asphalt emulsified mortar construction on track slab geometry status [PDF]

open access: yesRailway 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 ...

Random-Forest Machine Learning Approach for High-Speed Railway Track Slab Deformation Identification Using Track-Side Vibration Monitoring

open access: yesApplied Sciences, 2021
High-speed railways (HSRs) are established all over the world owing to their advantages of high speed, ride comfort, and low vibration and noise. A ballastless track slab is a crucial part of the HSR, and its working condition directly affects the safe ...

Influence of temperature gradient of slab track on the dynamic responses of the train-CRTS III slab track on subgrade nonlinear coupled system

open access: yesScientific 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.

Energy harvesting from railway slab-tracks with continuous slabs

open access: yesJournal of Vibration and Control, 2021
This paper contributes to the literature and development of knowledge in the topic of energy harvesting by presenting the modelling and calculations of energy from vibration of railway tracks due to moving trains on floating-slab tracks with continuous slabs, considering both the quasi-static and dynamic effects. The floating-slab track is modelled as
