    Influence of High-Speed Flow on Aerodynamic Lift of Pantograph at 400 km/h by Zhao Xu, Hongwei Zhang, Wen Wang, Guobin Lin

    Published 2025-07-01

    This study examines pantograph aerodynamic lift at 400 km/h, and uncovers the dynamic behaviors and mechanisms that influence pantograph–catenary performance. Using computational fluid dynamics (CFD) with a compressible fluid model and an SST k-ω turbulence model, aerodynamic characteristics were an...
