Dynamic Performance Simulation and Stable Current Collection Analysis of a Pantograph Catenary System for Trolley Wire Overhead Electrically Actuated LHD

Energies, 2020
The pantograph catenary system plays an important role in the power performance of electric mining vehicles. A pantograph catenary system combining both a pantograph and a catenary is one of the most promising solutions.

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 ...

Hierarchical Reinforcement Learning for Long‐Distance Multi‐Objective Optimization of Heavy‐Haul Trains via Sequential Task Assignment Across Spatial Segments

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
This paper proposes a sequential multi‐task collaboration hierarchical reinforcement learning framework for dynamic multi‐objective optimization of long‐distance heavy‐haul train operations. By decomposing the route into segment‐specific subtasks and coordinating sequential policy invocation through a top‐level dynamic programming framework, the ...

FCDM‐Net: A Feature‐Calibrated Dynamic Masking Network Based on Pre‐Trained Models for Few‐Shot Catenary Component Anomaly Detection

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
This paper proposes a novel feature‐calibrated dynamic masking network (FCDM‐Net) for the unified few‐shot anomaly detection of catenary components. First, a lightweight residual adapter is integrated with a frozen visual encoder. Through a few‐shot fine‐tuning strategy, the general visual features are mapped to the specific manifold space of catenary ...

EMUs Pantograph Aerodynamics Experimental Research in Dropping Status under Strong Wind Condition

机车电传动, 2016
When EMUs run at a high speed, the pantograph would be affected by airflow and blown up in dropping status, which would result in catenary short-circuit fault. In order to evaluate the pantograph aerodynamics characteristics in dropping status and ensure

Active Power Filter‐Based Low‐Frequency Ripple Power Suppression of the DC‐Link in Railway Traction Systems

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
This article presents an active power filtering control method to suppress ripple power in the DC‐link of railway traction systems, including both the inherent second‐order ripple of single‐phase rectifiers and additional frequency ripples introduced by the pantograph–catenary arc.

Uniqueness Theorem and Midpoint Numerical Technique for Fractal‐Fractional Differential Equations With Power Law Kernel

Journal of Applied Mathematics, Volume 2026, Issue 1, 2026.
In this paper, we obtained conditions for the uniqueness of solution and a Crank–Nicholson–type algorithm for fractal‐fractional differential equations with a power law kernel in Riemann–Liouville sense. For the uniqueness analysis, Kooi′s conditions are imposed on the problem.

Analytical Investigation of Fractional Nonlinear Systems in Compact‐Open Banach Spaces: Applications in the Chemical Wave Propagation Theory

Journal of Mathematics, Volume 2026, Issue 1, 2026.
In this work, we present some analytical and topological framework for fractional nonlinear systems on compact‐open Banach spaces. By using the locally compact property of these spaces, the continuity and compactness of nonlinear operators are rigorously established.
