Abstract

High-speed railway overhead systems are subjected to tight functional requirements to deliver electrical energy to trains while their reliability and maintenance periods have to be increased. The quest for interoperability of different pantographs in existing and projected catenary systems puts an extra level of demand on the ability to control their interface, which can only be addressed by reliable, efficient and accurate computational tools. This work overviews the features required for the computational methods used in the analysis of the catenary-pantograph interaction, discusses minimal requirements for model construction and presents some recent applications to existing high-speed overhead systems.
