Abstract

Proper pantograph-catenary interaction is an important factor for providing constant power supply to an electrified train, especially at high speed railways. In this paper, the author presents results of his study on improving pantograph-catenary system dynamic interaction by means of using alternative collector head suspension springs. The multi-domain co-simulation numerical set-up presented previously by the author was employed in the investigation presented in this paper. Precise stiffness and damping properties of collector head suspension springs were designated from validated numerical model. In total, 40 alternative suspension springs were considered, and the most favourable ones are indicated. The achieved results confirm, that pantograph-catenary dynamic interaction at high speed of travel can be improved by tuning the properties of collector head suspension properties, especially at design stage of a pantograph (in virtual prototyping approach). However, it is necessary to analyse the parameters of real springs, because it guarantees that specific parameters relating to specific springs are tested.
