Influence of Subgrade Settlement on Dynamic Characteristics of CRTS II Slab Orbit
In this paper, considering the structure and technical characteristics of CRTS-II-type slab track, we simplified the vehicle system and the track system accordingly, and by the method of coupling dynamics of wheel and rail system and finite element, as well as the help of ABAQUS finite element software, a vertical dynamic analysis model of vehicle-track-subgrade coupling is established. And the geometric irregularity of orbit is used as the source of system excitation, To study the influence of dynamic characteristics of vehicle–track system and system considering the long-wave irregularity and short-wave irregularities, uneven settlement, subgrade under different speed, on the basis of this study, some reasonable suggestions are put forward for the design of the future track structure.
