Reduction in aerodynamic noise emitted from a pantograph is an important subject for reducing environmental impact and speed-up of Shinkansen trains. In this study, applying condition, i.e. effective porous diameter and partial embedded domain, of porous material to pantograph head support considering bidirectional aerodynamic noise reduction was investigated. As a result, it is clarified that difference of diameter of porous cell does not affect aerodynamic noise reduction. Furthermore, partial embedded domain for porous material are proposed.
