In this paper, study of high speed train pantograph panhead shape for aerodynamic drag and noise reduction is performed. In previous research, it is known that pantograph arm and panhead are main sources of noise from high speed train pantograph. Numerical simulation using full scale pantograph model with streamlined cover at knee and optimized cross section of arm are performed for aerodynamic drag and noise reduction. In this study, first, cross section of pantograph panhead optimization are performed. Second, numerical simulation using full scale pantograph model with optimized cross section of pantograph panhead are performed. As a result, Aerodynamic drag and noise are reduced.
