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.

Modelling of Floating-Slab Track with Discontinuous Slab [PDF]
Journal 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]
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 ...

Energy harvesting from railway slab-tracks with continuous slabs
Journal 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
