The aerodynamic features of a pantograph of a high speed train are analyzed according to shapes of pantograph covers. For this purpose, two types of pantograph covers were selected: a wedge type cover and a cone type cover.
Then, the change of the aerodynamic forces of the pantograph affected by each type of the pantograph cover was computed. These results were compared with the original lift force of the pantograph. From the results, the cone type cover changes the flow direction from side to side compared with the wedge type cover. Consequently, it is confirmed that the effect of the wedge type cover on the lift force of pantograph is smaller than that of the cone type cover.
