Influence of unsupported sleepers on the dynamic stability of ballasted bed based on wheelset impact tests

open access: yesRailway Engineering Science, 2023
The unsupported sleeper can change the load characteristics of ballast particles and thus affect the dynamic stability of a ballasted bed. In this work, a laboratory test was constructed on a ballasted track containing unsupported sleepers. The ballasted

Qualitative Prediction Model for Dynamic Behavior of Ballasted Tracks

open access: yesApplied Sciences, 2020
Theoretical, experimental, analytical, and statistical evaluations were performed to predict and assess the dynamic behavior of a ballasted track, such as the track support stiffness, track impact factor, or dynamic wheel–rail forces.
