Analysis of mesoscopic mechanical dynamic characteristics of ballast bed with under sleeper pads
Abstract The meso-dynamical behaviour of a high-speed rail ballast bed with under sleeper pads (USPs) was studied. The geometrically irregular refined discrete element model of the ballast particles was constructed using 3D scanning techniques, and the 3D dynamic model of the rail–sleeper–ballast be...
