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 ... -
Heuristic models for wear prediction and dynamic-based condition monitoring techniques in pantograph-catenary interaction
Derosa, Stefano (Doctoral theses at NTNU;2020:381, Doctoral thesis, 2020)Railway catenaries are key components of electric railways, representing for the trains both their power source and their performance limiter. Although the amount of electrified railways is noticeably lower than the ... -
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 ... -
Railway catenary tension force monitoring via the analysis of wave propagation in cables
Derosa, Stefano; Nåvik, Petter Juell; Collina, Andrea; Rønnquist, Anders (Peer reviewed; Journal article, 2020)The tensioning forces applied to the contact wire in a railway catenary system influence the performance of the line. In this paper, a method to monitor the status of such tensioning forces is proposed based on the dependency ...
