The pantograph is modelled by a point load, which moves uniformly along the contact cable.
Using the proposed method, the steady-state deflection of the contact cable is analyzed thoroughly.
This model is capable of describing a coupled wave dynamics of both the carrying cable and the contact cable of the catenary.
Additionally, the contact force between the hangers and the contact cable is studied, which is important for estimation of the fatigue life of the hangers.
