( ) , , . (.): We implement a composite procedure on the basis of combined approach for modeling aerodynamic loads on infrastructure elements (station constructions and designs, pedestrian crossings, bridges and tunnels) at passage of high-speed trains. We develop and implement in specialized software powerful methods of viscous liquid or gas currents modeling for research of aerohydrodynamic loads on a movable body of varying shape, and for problems of body movement in the presence of aerodynamic forces. : 4639, : 1191, : 7. |
