With the rapid development of urban rail transit, the design of track system should take into account of the safety, ride quality of train, durability of track, maintain of environmental friendship simultaneously. Conventional design methods usually focus on detailed type selection of rail, fasteners, turnouts, track bed, and vibration mitigation tracks. Experiences revealed that the conventional methods were deficient in enhancing the combinational dynamic property of coupled train-track system. Based upon the theory of vehicle-track coupling dynamics, an advanced computer simulation technology was proposed. The paper systematically and briefly presents the application of the method that be used to study the effects induced by geometric and stiffness irregularity, transition sections, rail corrugation, and dynamic parameters of vibration mitigation track to the train-track system.
