Experimental study of electrical characteristics on pantograph arcing

, 2011
Perfect sliding electrical contact between pantograph and catenary can guarantee the safety and stability of locomotive. Pantograph arcing is one of the main factors of sliding electrical contact performance in electrified railway system. The main reason

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. An insulated

Scanner‐agnostic dynamic jaw motion generation from virtual static excursive records using open‐source Python‐based artificial intelligence (AI) interpolation

Journal of Prosthodontics, Volume 35, Issue 3, Page 407-413, March 2026.
Abstract This technique describes a scanner‐agnostic digital workflow for generating dynamic mandibular motion from static virtual interocclusal records using a custom artificial intelligence (AI) algorithm and user interface. Virtual records of mandibular positions, including maximum intercuspation, protrusion, and lateral excursions, were captured ...

Introduction of variability in pantograph-catenary dynamic simulations [PDF]

, 2013
Currently, pantograph-catenary dynamic simulations codes are mainly based on deterministic approaches. However, the contact force between catenary and pantograph depends on many key parameters that are not always quantified precisely.

Heavy‐Haul Railway Alignment Design Considering the Heavy‐to‐Light Ratio and Regenerative Braking Energy

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
This study proposes an NSGA‐II framework enhanced with struct‐based encoding for bi‐objective optimization of heavy‐haul railway vertical alignment (construction cost and energy consumption), which requires no preset vertical points of intersection (VPIs) and inherently meets most constraints.

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 ...
