Given the high costs related to the homologation processes of rolling stock, this project proposed the design and assembly of a Hardware-In-the-Loop (HIL) test bench to simulate the dynamic interaction between pantograph and catenary. The latter was replaced by a virtual finite element model, which was solved in real time, and a linear actuator that reproduced the position of the contact point on the pantograph. For this, it was necessary to have catenary models that were as realistic as possible and whose dynamic resolution had a very low computational cost. The aim of this methodology was to contribute to the reduction of pantograph homologation costs by conducting laboratory tests.
