The aerodynamic performance of the pantograph of the next generation high speed train is analyzed. The calculation of the flow around pantograph is carried out by FLUENT; by the steady state flow calculation with κ-ω SST turbulence model, the lift force of the pantograph is computed. For the verification of the numerical schemes and grid systems, flow calculations are performed with the pantograph shape which was used at the experiments performed at Railway Technical Research Institute (RTRI) in Japan. Then, the difference of lift force between numerical and experimental results is about 10%. Therefore, selected numerical schemes and the current grid system is adequate for the analysis and prediction of the aerodynamic performance of pantograph system. Based on these numerical schemes and grid systems, the flow around a pantograph of the next generation high speed train is calculated and the lift force of the pantograph is predicted; the lift force of the pantograph is about 146N.
