Dynamic responses of vehicle ballasted track interaction system for heavy haul trains [PDF]
MATEC Web of Conferences, 2018 In this study, the dynamic responses of ballasted tracks subjected to heavy haul trains are investigated. The vehicle ballasted track interaction (VTI) model can be divided into three parts, which are vehicle model, ballasted track model and wheel/rail ...

Dynamic Properties Evaluation of Railway Ballast Using Impact Excitation Technique
Proceedings, 2018 Railway ballasted track, traditional railway track, consists of steel rails, sleepers, fastener system, ballast, sub-ballast and subgrade. Railway ballasted track has been widely used in railway system around the world.

Qualitative Prediction Model for Dynamic Behavior of Ballasted Tracks
Applied 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.

The interaction between railway vehicle dynamics and track lateral alignment [PDF]
, 2016 Track geometry deteriorates with traffic flow, thus it needs to be regularly restored using tamping or other method. As the deterioration is mainly in the vertical direction this aspect has been widely studied and models for its analysis developed ...

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

Advances in Materials Science and Engineering, 2022 Due to the complex dynamic interactions of the vehicle-track system in the turnout of high-speed railway stations on a ballasted track, the geometric position of the line changes rapidly. In order to improve the stability of the line, the ballasted track
