STUDY OF DYNAMICS OF PRESSURE ON THE SURFACE OF THE TRAIN ON DOUBLE-TRACK TUNNEL UNDERGROUND

The article presents the procedure and results of the study parameters of ambient air during the motion of a single train on the double-track underground tunnel. The dynamics of the pressure in the air volume of the tunnel, on the front surface of the front and tail of the train.
The research was carry out by numerical modeling in the internal volume of double-track tunnel for moving trains using finite element method. The research’s result: graphical dependence of the static pressure on the frontal surface of the head and tail of a single wagon train in a double track tunnel from the speed of the train.

Keywords

Underground, double-track tunnel, piston action, computational simulation, aerodynamical processes, pressure.
