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 ...

Evolution of the electrical contact of dynamic pantograph–catenary system [PDF]

Journal of Modern Transportation, 2016
A good contact between the pantograph and catenary is critically important for the working reliability of electric trains, while the basic understanding on the electrical contact evolution during the pantograph–catenary system working is still ambiguous so far.

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 ...

The Generating Mechanism and Suppression Measure of the ‘Wheel‐Rail’ Rolling Arc for Electrified Trains

High Voltage, Volume 11, Issue 2, Page 370-384, April 2026.
ABSTRACT As the ‘main blood vessel’ of the traction power supply system for high‐speed trains, the ‘wheel‐rail’ coupling grounding reflux system provides the vital channel to send traction current back to terrestrial substations; meanwhile, the rail track also plays a role in transmitting the train's occupancy signal to the control system.

Dual‐Frequency Piezoelectric Vibration Energy Harvester for IoT‐Based Real‐Time Freight Train Health Monitoring in Mongolia

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
This study evaluates the potential of piezoelectric vibration energy harvesting to power IoT nodes for real‐time health monitoring of the Mongolian railway. Triaxial vibration data were collected at 500 Hz over a 400 km freight route under loaded and unloaded conditions using a custom ESP32‐S3 + MPU9250 system, and dominant frequencies were extracted ...

Statistical identification of geometric parameters for high speed train catenary [PDF]

, 2014
Pantograph/catenary interaction is known to be strongly dependent on the static geometry of the catenary, this research thus seeks to build a statistical model of this geometry.
