Ballast Flying DEM Microscopic Analysis and Counteracting Measures

Abstract:

Article Preview

Ballast flying problems obsess the high speed railway developments, causing damages to the train and deteriorations to the rail. In the paper, DEM is used to conduct ballast flying mechanism microscopic study, results show ballast flying increases with train dynamic force, and decreases with ballast size and friction coefficient, ballast flying counteracting measures are presented, such as ballast bed parameter and ballast glue. In the end, future possible microscopic ballast flying model method is presented by DEM coupled with CFD.
