As the maximum speed of Shinkansen increases, it becomes more important to resolve aerodynamic problems relating to a pantograph. These problems are related with shape of pantograph panhead. In the previous study, the shape of the panhead was designed by an optimizing method with CFD. The purpose of this study is to develop a new kind of wind tunnel model to obtain aerodynamic characteristics of various cross-sectional shapes for experimental shape-optimization. Wind tunnel testing was carried out to estimate the efficiency of the model. As a result, it has been confirmed that aerodynamic characteristic of the developed wind tunnel model which is composed of film and frame agrees well with that of solid model.
