Dynamic responses of vehicle ballasted track interaction system for heavy haul trains
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 ...

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

Experimental Study on Settlement Behavior of Ballasted Tracks with Polymer Compound-Coated Gravel
The ballast used in ballasted railway tracks transmits load from the rails and ties to the subgrade during train travel, and directly affects the overall track support performance and elastic behavior of the ballasted track.
