Study on abnormal abrasion of metro pantograph

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 ...

A Numerical Study on Pantograph Raising and Lowering in Multi-Pantograph Operation

, 2017
Multi-pantograph operation is a convenient and efficient way to operate railway rolling stock and infrastructure, but the influence between the pantographs makes the system more sensitive and vulnerable than a single-pantograph system.

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.

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.
