English abstract:
In this paper, a novel approach for the simulation of the railway catenary and
pantograph dynamics is proposed. The partial di erential equations describing the vertical
motion of the contact and carrier wires of the catenary are transformed in such a way that the
pantograph is at rest with respect to the new moving coordinate. The computational domain is
then truncated and absorbing boundary conditions are applied. High computational performance
due to a great reduction in variables is achieved. The di erences between this small scale system
and a reference system with a xed catenary length and a moving pantograph are investigated.
