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

open access: yes, 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.

Classifying Power Quality Issues in Railway Electrification Systems Using a Nonsubsampled Contourlet Transform Approach

open access: yesEngineering Reports, Volume 7, Issue 8, August 2025.
Railway electrification systems indeed have unique challenges due to variable power demand and dynamic train operations. Power quality (PQ) monitoring for high‐speed trains (HSTs) is essential to guarantee the effectual and unfailing operation of the ESs.

Reducing method of aerodynamic noise from high speed pantograph.

open access: yesTRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1985
The aerodynamic noise from pantograph is one of the important external noise source of a high speed train as Shinkansen. The external noises of testing trains were measured using a linear-array type directional microphon and a full-scale pantograph was tested in a low noise wind tunnel. It is shown that the intensity of the pantograph aerodynamic noise

Strain Amplification via Helically Braided Fiber Reinforced Sleeve for Soft Material Energy Harvesting

open access: yesAdvanced Materials Technologies, Volume 10, Issue 13, July 8, 2025.
This study presents a braided fiber‐reinforced sleeve that amplifies strain in soft materials, enhancing their performance in stretchable devices like sensors and energy harvesters. By reinforcing and elongating encased materials, the sleeve increases the “effective” strain.

Analysis of flow velocity fluctuation around a train model running in a tunnel using restored waveforms

open access: yesMechanical Engineering Journal, 2021
A pantograph receives aerodynamic force while a train is traveling. As the aerodynamic force increases in proportion to the square of the flow velocity relative to the pantograph, its influence on the pantograph becomes apparent, especially for high ...
