Dynamic performance of low vibration slab track on shared high-speed passenger and freight railway

open access: yesTransport, 2018
This work investigates dynamic performance of a low vibration slab track on a shared high-speed passenger and freight railway, and an optimal modulus of the isolation layer (rubber pad) is proposed to meet the adaptability of the track system under the ...

Study on the threshold for superposed deformation of simply supported bridge creep and track slab upwarp in high-speed railway

open access: yesAdvances in Mechanical Engineering, 2022
Based on long-term inspection data about track geometric irregularity of 32 m-span simply supported girder bridge in China Railway High-Speed for nearly 10 years, it is found that there is continuous periodic track longitudinal level (TLL) with different

Slab track optimisation considering dynamic train–track interaction [PDF]

open access: yes, 2021
Slab track is a type of railway track that is frequently used e.g. in high-speed applications as an alternative to ballasted track. Slab track is also well suited on bridges and in tunnels since no ballast is required and the cross-section of tunnels can

The Interaction Between Railway Vehicle Dynamics And Track Lateral Alignment [PDF]

open access: yes
This thesis examines the effect of vehicle dynamics on lateral deterioration of the track alignment. As rail traffic runs along a route, the forces imposed upon the track cause the ballast to settle, and hence the track geometry deteriorates.

Effect of temperature gradient-induced periodic deformation of CRTS Ⅲ slab track on dynamic responses of the train-track system [PDF]

open access: yesRailway Sciences
Purpose – Temperature is an important load for a ballastless track. However, little research has been conducted on the dynamic responses when a train travels on a ballastless track under the temperature gradient.

Effects of Differential Subgrade Settlement on Slab Track Deformation Based on a DEM-FDM Coupled Approach

open access: yesApplied Sciences, 2021
Slab track structures become deformed under the effects of differential subgrade settlement. According to the properties of the China Railway Track System (CRTS) II slab track on a subgrade, a three-dimensional (3D) coupled model based on both the ...
