M. Podworna, M. Klasztorny, "Random Vibrations of a Bridge - Track Structure - High Speed Train System", in , (Editors), "Proceedings of the Fourteenth International Conference on Civil, Structural and Environmental Engineering Computing", Civil-Comp Press, Stirlingshire, UK, Paper 20, 2013. doi:10.4203/ccp.102.20

Keywords: steel-concrete composite bridge, ballasted track structure, ICE-3 high-speed train, random track irregularities, modelling, numerical analysis.

Summary

In this paper, a theory of the quasi-exact physical and mathematical modelling of the composite (steel-concrete) bridge / track structure / high-speed train system (BTT) is developed including viscoelastic suspension of rail-vehicles on two-axle bogies, the non-linear Hertz contact stiffness and one-sided contact between the wheel sets and rails, the viscoelastic and inertia features of the bridge, the viscoelastic track structure on and beyond the bridge, the approach slabs, and random track irregulari-ties. Based on this theory, advanced computer algorithms for the BTT numerical modelling and a computer program to simulate the vertical vibrations of the BTT systems is developed. The bridge under the preliminary dynamic analysis, designed according to Polish standards, has a 15m span length and the assigned code SCB-15. The bridge is loaded using the German ICE-3 high-speed train moving at the resonant and maximum operating speeds.
