Environmental and track perturbations on multiple pantograph interaction with catenaries in high-speed trains [PDF]

open access: yes, 2013
The top velocity of high-speed trains is generally limited by the ability to supply the proper amount of energy through the pantograph-catenary interface.

Synchronized Measurement System for Railway Application [PDF]

open access: yes, 2018
In the light of the recent European directives that regulate railway networks in EU, in order to implement the monitoring and controlling of the railways power supply network, an accurate and reliable knowledge of the exchanged energy between the train

Dynamic analysis using finite elements to calculate the critical wear section of the contact wire in suburban railway overhead conductor rails [PDF]

open access: yes, 2008
The purpose of this study is to determine the critical wear levels of the contact wire of the catenary on metropolitan lines. The study has focussed on the zones of contact wire where localised wear is produced, normally associated with the appearance of

Enhancing pantograph-catenary dynamic performance using an inertance-integrated damping system [PDF]

open access: yes, 2021
For modern electrical rail systems, the pantograph-catenary dynamic performance is one of the most critical challenges. Too much fluctuation in contact forces leads to either accelerated wear of the contacting components or losses of contact and ...

Fatigue analysis of catenary contact wires for high speed trains [PDF]

open access: yes, 2011
The fatigue fracture is one of the most critical failures which may occur on the high speed network because it is undetectable and it has a huge impact on traffic disruption.

Study on abnormal abrasion of metro pantograph

open access: yes机车电传动, 2023
Pantograph-catenary system is the central system for the power supply of urban rail transit trains. Higher train speed and complex train operating environment can generate severe vibrations on the pantograph-catenary system, resulting in high-frequency ...

Characteristics of pantograph‐catenary arc under low air pressure and strong airflow

open access: yesHigh Voltage, 2022
Pantograph‐catenary arc fault is the primary factor threatening the stability of the power transmission for high‐speed railway. The motion characteristics of the pantograph‐catenary arc under low air pressure and strong airflow is significantly different

Assessment of the Current Collection Quality of Pantograph-Catenary with Contact Line Height Variability in Electric Railways [PDF]

open access: yes, 2021
The numerical tools are widely used to facilitate the design of the railway catenary. Only radical results are obtained as the current assessment is generally performed without any practical errors.

Electrical capturing system for train supplying and involving parameters

open access: yesMaterials and Devices, 2022
Electric trains are powered by a current distribution device which depends on several parameters. The research works presented in this paper are located upstream of two types of important applications in the railway field: the electrical supply of trains
