Effect of Pantograph’s Main Structure on the Contact Quality in High-Speed Railway

Shock and Vibration, 2021
In general, the electrical energy is provided to the high-speed train through the pantograph-catenary sliding contact. The variation of the dynamic contact force is expected to be small enough to keep the good current collection quality and to extend the

Modeling and Simulation of the Aerodynamic Noise of High‐Speed Train’s Pantograph

Journal of Engineering, Volume 2022, Issue 1, 2022., 2022
This article aims to investigate the aerodynamic noise of the pantograph of the high‐speed trains in different operating conditions. CFD technique was used to assess the acoustic noise of the pantograph components. Three‐dimensional computational simulations were performed using FLUENT software.

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

Journal 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 ...

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

IEEE 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.

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

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

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 ...
