A robust line-tracking photogrammetry method for uplift measurements of railway catenary systems in noisy backgrounds [PDF]
, 2020 For electrical railways, contact wires are used to ensure stable and continuous power supply to trains operating on the infrastructure. One crucial design parameter used to control the catenary design is the vertical displacement.

Damping characterization of a high speed train catenary [PDF]
, 2015 Catenary damping has long been a tuning parameter in pantograph-catenary dynamic interaction models. As the computed contact force is highly sensitive to the choice of damping model or coefficients, it became critical to measure it independently of the ...

Numerical Analysis of the Dynamic Behaviour of Railway Catenary Systems in Accordance with Norwegian Conditions [PDF]
, 2013 The dynamic behaviour of the railway catenary system is of great importance as the speed of the train increases. The aim for this study was to make a numerical model of the catenary system in three dimensions to be able to investigate what should be done

Arc Erosion Behaviors of Pantograph of High-Speed Train During Its Rise and Fall Processes
IEEE AccessArc melting pools are generated when the pantograph and catenary (PAC) are offline during the rise and fall of the pantograph. They can lead to the material damage, accelerated wear, increased splashing, and exacerbated PAC fatigue through the thermal ...
