Modeling of Coupling Mechanism between Ballast Bed and Track Structure of High-Speed Railway
In this paper, a discrete and continuous body coupling algorithm is used to study the dynamic contact characteristics between ballasts and between ballasts and track structures. Firstly, the three-dimensional fine modeling of ballast particles is realized based on the three-dimensional laser scannin...
