Influence of Piston Wind on Contact Wires Aerodynamic Performance
By using software Star-CD and dynamic meshing technique, the two-dimensional models of blunt-shaped and streamlineshaped train passing through tunnel with different speed were built. The piston wind property and the influence of the piston wind on catenaries contact wires aerodynamic performance wer...

| description | By using software Star-CD and dynamic meshing technique, the two-dimensional models of blunt-shaped and streamlineshaped train passing through tunnel with different speed were built. The piston wind property and the influence of the piston wind on catenaries contact wires aerodynamic performance were analyzed. When the height of contact wires was 6 meter, the maximum value of the piston wind vertical components and the lift forces on contact wires formed by the blunt train were twice and quadruple of that formed by the streamline train. When the speed of train increased ten meters per second, the maximum lift force on contact wires would double. |
