Experimental stand and researches on pantograph-catenary contact force control using chaos theory

open access: yesJournal of Physics: Conference Series, 2021
Abstract Due to the oscillating behaviour of the pantograph and the catenary during the movement of the locomotive, the contact force changes to wide limits, resulting in electrical sparks with consequences: premature wear of the contact wire, electromagnetic disturbances, energy loss.

Carbon brush wear calculation in marine environment based on temperature field analysis

open access: yesIET Renewable Power Generation, Volume 16, Issue 11, Page 2267-2278, 17 August 2022., 2022
Abstract In the marine environment, the working environment of the doubly fed wind generator carbon brush and slip‐ring system is complicated, salt spray deposits and seawater erosion affect the temperature field and contact surface friction factor leading to carbon brush wear increase and shortened replacement cycle.

Study on electric spark discharge between pantograph and catenary in electrified railway

open access: yesIET Electrical Systems in Transportation, Volume 12, Issue 2, Page 128-142, June 2022., 2022
Abstract The electric spark caused by pantograph‐catenary (PC) electrical contact failure happens frequently, it is a kind of arcing phenomenon which can severely affect the current collection of PC. The theoretical analysis and modelling of PC electric spark are tried.

Estimator-based H∞ control considering actuator time delay for active double-pantograph in high-speed railways

open access: yesJournal of Low Frequency Noise, Vibration and Active Control, 2021
When two electric multiple units are non-electrically connected together for improving the transport capacity in high-speed railways, double pantographs frequently operate simultaneously to decrease the current capacity on a single pantograph collector ...

Pantograph Catenary Contact Force Regulation Based on Modified Takagi-Sugeno Fuzzy Models

open access: yesEngineering, Technology & Applied Science Research, 2023
In this paper, a new contact force control technique, based on the modified Takagi-Sugeno model and the parallel distributed compensation concept is developed to suppress vibrations between the pantograph and the catenary by regulating the contact force to a reference value, thereby achieving stable current collection.

A New Active Control Strategy for Pantograph in High-Speed Electrified Railways Based on Multi-Objective Robust Control

open access: yesIEEE Access, 2019
In high-speed railways, the quality of current collection of high-speed train is directly determined by the contact force between the contact wire of the catenary and the registration strip of the pantograph.

Finite element analysis of pantograph-catenary dynamic interaction [PDF]

open access: yesArchives of Transport, 2016
Numerical simulations of the pantograph-catenary dynamic interaction allow for assessment of the current collection quality provided by this subsystem at the design stage of the pantograph or the catenary system.

Optimization of dynamic parameters of straddle monorail vehicle to improve pantograph-catenary contact quality

open access: yes机车电传动, 2022
Because straddle monorail vehicles run on rubber wheels, the contact status between the pantograph and the catenary is hard to control, and the abrasion on the current-receiving sliding block on the pantograph is serious.

Multi-field coupling modeling and temperature rise analysis for the static pantograph-catenary electrical contact of metro trains

open access: yes机车电传动, 2023
Since the catenary still needs to supply current for the trains stopping at stations or stopping temporarily on the track for some reasons, the pantograph-catenary contact part in a stationary state may suffer from overheat, which may lead to a thermal ...
