Abstract
It is well-known that the wind speed affecting the pantograph is stronger in
tunnels than in the open air on the Shinkansen line. Therefore, the authors
measured wind speed, wind direction, dynamic behavior of the overhead
contacts line and metal fittings when the Shinkansen train ran through a tunnel at
high-speed. This paper discusses the influence of the air flow in a tunnel caused
by a high-speed train on current collection performance and the overhead
contacts lines. Further, the aerodynamic upward force of the pantograph was
estimated on the basis of the measured results. Finally, using the motion
simulation of a pantograph and overhead contacts line, their dynamic
characteristics at high-speed were evaluated.
Keywords: electric railway, current collection, overhead contact line, tunnel,
train draughts, upward force of the pantograph.
