The pantograph lift measurement method in overhead catenary system
Nihon Kikai Gakkai ronbunshuCondition monitoring technology has advanced remarkably in recent years in various areas, including railways. Since the overhead catenary system and the pantograph in railway does not have enough redundancy, failures of the overhead catenary system or ...

Dynamic Analysis of Pantograph-Catenary System considering Ice Coating
Shock and Vibration, 2020 Ice coating on overhead contact system (OCS) will affect the sliding of pantograph, and arc discharge phenomena will occur between pantograph and catenary, which will threaten the normal operation of train.

Pantograph/Catenary Contact Formulations [PDF]
, 2016 In this investigation, the pantograph/catenary contact is examined using two different formulations. The first is an elastic contact formulation that allows for the catenary/panhead separation and for the analysis of the effect of the aerodynamic forces,

Introduction of variability into pantograph–catenary dynamic simulations [PDF]
, 2014 Currently, pantograph-catenary dynamic simulations are mainly based on deterministic approaches. However, the contact force between catenary and pantograph depends on many key parameters that are not always quantified precisely and can vary in time and ...

The pantograph-catenary arc test system for high-speed railways
, 2012 High speed electric multi units (EMU) get power through pantograph-centenary electrical contact. As the EMU running velocity increases, rail surface irregularities, undulations of the catenary and vibrations of the pantograph head cause the status of ...
