Dynamic behaviour of existing and new railway catenary systems under Norwegian conditions
Nåvik, Petter Røe (Doctoral theses at NTNU;2016:298, Doctoral thesis, 2016)This thesis concerns the dynamic behaviour of railway catenary systems, particularly Norwegian systems. The aim of this PhD study is to increase the knowledge of the dynamic behaviour of these systems. This includes analyses ... -
Dynamic comparison of a railway catenary section upgrade by field measurement assessments
Nåvik, Petter Røe; Rønnquist, Anders (Journal article; Peer reviewed, 2017)The pantograph-catenary interaction is crucial for running trains on electrical railway lines. The coupled dynamic problem of an in space stationary system, the catenary system, and a system in motion, the pantograph, is ... -
Dynamic Identification and Modelling of a Pantograph
Knutzen, Anders Nygaard; Sivertsen, John-Arne Berg (Master thesis, 2018)The main objective of this thesis is to measure and determine the dynamic properties of a measurement pantograph, and then create a numerical model with the same properties. The purpose of the model is to give a better ... -
Numerical Analysis of the Dynamic Behaviour of Railway Catenary Systems in Accordance with Norwegian Conditions
Nåvik, Petter Røe (Master thesis, 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 ... -
Variation in predicting pantograph–catenary interaction contact forces, numerical simulations and field measurements
Nåvik, Petter Røe; Rønnquist, Anders; Stichel, Sebastian (Journal article; Peer reviewed, 2017)The contact force between the pantograph and the contact wire ensures energy transfer between the two. Too small of a force leads to arching and unstable energy transfer, while too large of a force leads to unnecessary ...
