Dynamic Model of Subgrade Using a Coupled Vehicle-Track-Subgrade Method
It is very critical to understand the dynamic interaction of vehicle-track-subgrade for high-speed railway development. This paper presents a dynamic interaction model of vehicle-slab track-subgrade system, in which a slab track-subgrade structure is put forward as a substructure and is studied considering track irregularity excitation and displacement compatibility condition. In this model, both the actual structure of a vehicle and vibration characteristic of the substructure (including slab track, subgrade and foundation are) considered. This model not only reflects the interaction between vehicle and substructure completely, but also provides a theoretical foundation for determining design parameters of high-speed railway (especially for design parameters of track and subgrade). Research results can provide technical reference for design and construction of slab ballastless track and subgrade structure of high-speed railway.
