This paper describes the methodology proposed to define the aerodynamic loads acting on a rail carbody, for given turbulent wind conditions and to compute the corresponding vehicle's response. Experimental data of wind tunnel tests, together with numerical simulation results, are shown. Finally, the set up numerical model is adopted to estimate critical wind curves.

Abstract
This paper describes the methodology proposed to define the aerodynamic loads acting on a rail carbody, for given turbulent wind conditions and to compute the corresponding vehicle's response. Experimental data of wind tunnel tests, together with numerical simulation results, are shown. Finally, the set up numerical model is adopted to estimate critical wind curves.File in questo prodotto:
