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

open access: yes, 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.

A Design of an Axisymmetric Roof With a Horizontal Rotation Axis

open access: yesStudies in Applied Mathematics, Volume 156, Issue 1, January 2026.
ABSTRACT This research proposes a novel roof design whose shape follows the mathematical model of an ideal hanging surface. The resulting roof is a surface of revolution, but its rotation axis is horizontal, which challenges conventional intuition because the axis is perpendicular to the direction of gravity.

Research on the Influence of Straddle-Type Monorail’s Pantograph Head Parameter on Power Collection Quality

open access: yesUrban Rail Transit, 2017
At present, the coupling relationship between the pantograph and catenary is not ideal for straddle-type monorail. The power collection quality is poor, and the wear of the contact strip of a pantograph is uneven.

Comparison of Neuro‐Fuzzy and Neural Network Techniques for Estimating the Line Voltage of 8E Electrical Locomotives

open access: yesInternational Transactions on Electrical Energy Systems, Volume 2026, Issue 1, 2026.
The South African rail sector is a key contributor to the national economy, boosting gross domestic product (GDP) and creating jobs. However, serious malfunctions often jeopardize the reliability of locomotives such as the Class 8E locomotive, leading to lost output and longer lead times.

Study on abnormal abrasion of metro pantograph

open access: yes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 ...
