TL;DR: In this article, the authors classified the resonant responses of the bridge induced by moving trains into three types according to different resonance mechanisms: the first is related to the periodical actions of moving load series of the vertical weights, lateral centrifugal and wind forces of vehicles; the second is induced by the loading rate of moving loads of vehicles, and the third is due to the periodically loading of the swing forces of the train vehicles excited by track irregularities and wheel hunting movements.

TL;DR: In this article, the authors presented an onsite experiment of the train-track-bridge interaction dynamics carried out on the Beijing-Tianjin high-speed railway, and then the experimental results are used to validate the train -track-bridges interaction simulation software (TTBSIM).
Abstract: Experimental validation is a precondition for dynamic simulation of high-speed train–track–bridge interaction system to be applied to railway engineering in the field. The paper first presents an onsite experiment of the train–track–bridge interaction dynamics carried out on the Beijing–Tianjin high-speed railway, and then the experimental results are used to validate the train–track–bridge interaction simulation software (TTBSIM). There is a good correlation between the calculated results and the measured data. As a case study, the Yellow River Bridge in the Beijing–Shanghai high-speed railway is studied, from modelling of the bridge structure to evaluating the dynamic performance of the train–track–bridge interaction system under the CRH3 EMU passing through at speeds of 250–375 km/h. The calculated and measured results are also compared in the case of such a large steel bridge under high-speed moving train, demonstrating the effectiveness of the TTBSIM simulation for dynamic evaluation of complex bridg...

TL;DR: In this article, the dynamic interaction between high-speed train and simply supported girders is studied by theoretical analysis and field experiment in a train-bridge system, in which the rigid-body dynamics theory, finite element method and wheel-rail displacement corresponding assumption are adopted for the vehicle model, bridge model and wheelrail interaction model, respectively.

TL;DR: In this article, a formulation of three-dimensional dynamic interactions between a bridge and a high-speed train using wheel-rail interfaces has been developed, where contact loss is allowed, the vertical contact is represented by finite tensionless stiffness and the lateral contact is idealized by finite contact stiffness and damping.
