Development of a Numerical Model of the Aerodynamic Interaction of a High-Speed Train, Air Environment and Infrastructure Facilities

The design of high-speed railway lines (HSR) requires mandatory consideration loads from the aerodynamic interaction a moving train, air environment and infrastructure facilities, acting both on structures train itself. Software systems computational fluid dynamics are most expedient to determine nature intensity load. To find optimal approach modelling processes between environment, as well assess degree validity simulation, series calculations were performed in ANSYS CFX software using various approaches construction calculation models (the sliding grid method immersed solid method). An analysis results makes it possible area rational application considered development interaction. verify developed models, experimental measurements impact Sapsan electric performed. Also, verified based similar international studies. Comparison numerical simulation allows us conclude that sufficiently valid can be further applied.
