Contact point lateral speed effects on contact strip wear in pantograph – catenary interaction for railway operations under 15 kV 16.67 Hz AC systems
Derosa, Stefano; Nåvik, Petter Juell; Collina, Andrea; Bucca, Giuseppe; Rønnquist, Anders (Peer reviewed; Journal article, 2021)The design of a railway catenary is subject to multiple decisions regarding the geometry of the system. In particular, the horizontal geometry of the contact wire determines the evolution of the wear of the contact wire ... -
A heuristic wear model for the contact strip and contact wire in pantograph – Catenary interaction for railway operations under 15 kV 16.67 Hz AC systems
Derosa, Stefano; Nåvik, Petter Juell; Collina, Andrea; Bucca, Giuseppe; Rønnquist, Anders (Peer reviewed; Journal article, 2020)The sliding contact between the pantograph and catenary allows the correct operation of electric trains. However, this contact induces wear on both the components involved in the process, namely the contact strip on the ...
