Abstract Aiming to mitigate the aerodynamic lift force imbalance between pantograph strips, which exacerbates wear and
affects the current collection performance of the pantograph-catenary system, a study has been conducted to support the beam deflector optimization using a combination of experimental measurements and computational fluid
dynamics (CFD) simulations. The results demonstrate that the size, position, and installation orientation of the
wind deflectors significantly influence the amount of force compensation. They also indicate that the front strip
deflectors should be installed downwards and the rear strip deflectors upwards, thereby forming a “π” shape.
Moreover, the lift force compensation provided by the wind… More >
