Pantograph and overhead line aerodynamics is responsible for affecting the contact force between the pantograph and the contact wire, both in terms of average value and dynamic variation. Stationary forces acting on pantograph components can change the average value of the contact force, whereas aerodynamic non-stationary phenomena influence the performance of railway pantograph in terms of dynamic variation of the contact force. This paper is a first attempt of numerical evaluation of the dynamic effects introduced by unsteady aerodynamic forces on the pantograph-catenary dynamic interaction.
