In order to explore the influence of different particle size gradations dirty materials on service performance ballast bed, clean track completely fouled bed polluted by coarse coal and fine coal, respectively, were studied based discrete element method. multi-scale gradation material coarse-particle simulated, method, which are used analyze dynamic response under working conditions cyclic load. The model is verified lateral resistance vertical stiffness prove accuracy model. On this basis,...
The load generated during train operation is transmitted to sleepers through rails, and then from trackbeds. As one of the important components track structure, are very service-life safety railways. running speed will produce different frequencies on rails. To explore response under cyclical loads, this research used discrete element method simulate rails sleepers, realizes loading by applying cyclic loads was compression-failure test concrete sample verify reliability parameters model.
