Influence of Track Irregularities in the Catenary-Pantograph Dynamic Interaction [PDF]
, 2020 This paper presents an advanced pantograph-catenary-vehicle-track model, which allows us to analyze the vertical dynamics of the complete system. The developed model is able to evaluate the displacements and the contact force generated in the catenary ...

Pantograph-catenary interaction in curved railway tracks
, 2019 An approach for the dynamic analysis of pantograph-catenary interaction in curved tracks or in any generalized track trajectory is presented here. Both the catenary model and the trajectory path of the pantograph are consistent with the general geometry,
