摘要：
A detailed vehicle-track coupling dynamics model is established in this paper, based on the coupling dynamics theory and finite element method. The system model consists of vehicle model, track model (rail model and floating slab model), wheel/rail coupling model, and irregularity model. The simulation program is written, vehicle parameters and track structure parameters are input, and system dynamic responses are output. Based on the simulation results, the effects of vehicle speed, slab bearing parameters and track irregularities are studied, and vibration characteristics of floating slab track are analyzed in the paper. Some suggestions for the design and application of floating slab track are provided.
