Abstract

Maintaining consistent contact between the pantograph strips and the catenary wire is essential for smooth power delivery to the train. In this paper, aerodynamic loads acting on individual components of a HSX pantograph are investigated through the use of computational fluid dynamics. Both the lift and drag forces are monitored for the pantograph at three different operational heights of 320mm, 860mm, and 2100mm. With increasing height, both the total drag and lift forces are found to increase and the nature of lift force changes from providing a downward force to uplift at the maximum height tested.
