Abstract

Abstract

According to the structural characteristics of Bögle slab track, a new model of lateral finite strip and slab segment element was put forward, and the vertical vibration responses of high-speed train and Bögle slab track system were analyzed.In the model, the locomotive and trailer of high-speed train were regarded as multi-rigid body systems with two suspensions, based on the principle of total potential energy with stationary value in elastic system dynamics and the rule of "set-in-right-position" for formulating system matrixes, the vertical vibration equation set of the system was established, and the equation set was solved by Wilson-θ method. Computation result shows that the new model is correct and feasible, the differences between the vertical static displacements and dynamic displacements of rail and Bögle slab are 1.1×10^-2 mm and 2.0×10^-4 mm respectively, when train runs at 200 km·h^-1, the vertical vibration response waveforms and computation values of the system accord with corresponding physic concepts.
