Aerodynamic interaction between a panhead and an articulated system strongly affects aerodynamic and aeroacoustic characteristics of the Shinkansen pantograph. Hence, to clarify the features of the aerodynamic interaction is very important for developing a new pantograph and for its design. In this study, surface pressure field on the panhead were measured in a wind tunnel with pressure-sensitive paint (PSP) specially dispensed for use in low-speed range. This measurement provided detail information of pressure distribution on a panhead. As a result, some significant features of the aerodynamic interaction between the panhead and the articulated system were clarified, showing that the pressure measurements with PSP proved to be a powerful tool to estimate the aerodynamics interaction of the Shikansen pantograph system.
