S.M. Kaplunov, B.N. Chetverushkin, S.I. Doubinskiy, N.G. Valles, E.A. Dronova, "Modeling of Aerodynamic Loads on Infrastructure Elements for High Speed Trains", in J. Pombo, (Editor), "Proceedings of the Second International Conference on Railway Technology: Research, Development and Maintenance", Civil-Comp Press, Stirlingshire, UK, Paper 36, 2014. doi:10.4203/ccp.104.36

Keywords: separated flow, aerodynamic forces, bluff structures, discrete vortexes method, combined approach, numerical experiment, periodic vortex shedding.

Summary

This paper is devoted to the creation of mathematical models for the most dangerous oscillation excitation for tubes and cylindrical form bluff structures in liquid or gas cross flow, as well as for the creation of efficient computational methods for the description of these models. For modeling of aerodynamic loads on elements of the infrastructure (such as station construction, pedestrian crossings, bridges and tunnels) for the passage of high speed trains, an original combined method was applied. The method enables research on the aerodynamic loads applied to bodies that make arbitrary movements and to solve problems of body motion under aerodynamic forces.
