V. Polyakov, "Dynamic Interaction within a "Bridge-Track-Car" System on a High-Speed Railway", in J. Pombo, (Editor), "Proceedings of the Third International Conference on Railway Technology: Research, Development and Maintenance", Civil-Comp Press, Stirlingshire, UK, Paper 136, 2016. doi:10.4203/ccp.110.136

Keywords: high-speed railway, bridge dynamics, safety of motion, track, wearing, comfort, model.

Summary

This paper describes the problems that concern high-speed railway traffic on the bridges, overpasses and flyover zones. The complete model taking into account the vertical oscillation of the car body, trucks, wheels, rails with sleepers and superstructure of the bridge is considered. This model allows the estimation of various parameters of oscillation and dynamic interaction within the "bridge-track-car" system. The numerical experiments with the model enable the location of the sections of the railroad track where the ballast will be worn more rapidly and the moments when derailment possibly may occur.
