Abstract: This paper carries out basic research to advance the development of pantograph head which is more practical, excellent in low noise, and compatible with bidirectional operation. Wind tunnel tests were carried out using a two-dimensional model which simplified the cross-sectional shape of a pantograph head by installing small rods in the front and rear of the head, and the effect of rod installation was evaluated. The results clearly demonstrate that the installation of the rod significantly reduces the noise. Furthermore, the lift force of the pantograph head was found to be stable even when the angle of attack varied.

Keywords: Pantograph, aerodynamic noise, wind tunnel experiment.
