Pantograph/catenary contact force control

, 2015
In this paper, a new continuum-based pantograph/catenary model based on the absolute nodal coordinate formulation (ANCF) is proposed and used to develop an effective method to control the contact force which arises from the pantograph/catenary ...

Experimental Study on Anti-collapse Performance of Beam-column Substructure with Welded Flange-bolted Web Connection in Minor-axis Direction

工程科学与技术, 2018
Welded flange-bolted web connection is one of the common joints in the steel structure,and the mechanical performance and failure mode of the joint is related to the collapse resistance of steel frame closely.To compare and analyze the failure mode ...

Action-driven Reinforcement Learning for Improving Localization of Brace Sleeve in Railway Catenary

2020 International Conference on Sensing, Measurement & Data Analytics in the era of Artificial Intelligence (ICSMD), 2020
Brace Sleeve (BS) plays an essential role in connecting and fixing cantilevers of railway catenary systems. It needs to be monitored to ensure the safety of railway operations. In the literature, image processing techniques that can localize BSs from inspection images are proposed.

Enhanced Rabi Splitting of Exciton‐Polaritons and Plasmon‐Polaritons in Lithium Niobate Metasurface

Laser &Photonics Reviews, Volume 20, Issue 1, 8 January 2026.
This study presents an ultrathin lithium niobate metasurface capable of inducing highly sensitive Fano‐shaped resonances, enabling strong coupling with TMDC monolayers and plasmonic metamaterials/metasurfaces. Adjustable Q‐factors lead to controllable coupling strengths, achieving substantial Rabi splitting.

Integrated Traction and Guidance Control of Independently Rotating Wheelsets in Urban Rail Vehicles Using Flux‐Map‐Based Torque Reference Generation

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
Independently rotating wheelsets require accurate realization of traction and differential wheel torques under electrical constraints. This paper proposes a hierarchical control framework combining speed PI and LQ‐servo lateral guidance with scaling‐based torque allocation and a flux‐map current reference generator that accounts for DC‐link voltage ...

Study on the Component-Based Model of an All-Welded Beam-Column Connection for Progressive Collapse Analysis

Advances in Civil Engineering, 2020
The mechanical behavior of all-welded beam-column connections of steel frames during progressive collapse was numerically studied using finite element simulations. The validation of the numerical model was based on a previous test model.

Emergency Power Sharing by Using a Self‐Traction System in a Mass Rapid Transit Railway

IET Energy Systems Integration, Volume 8, Issue 1, January/December 2026.
ABSTRACT Systemwide traction power outages in mass rapid transit systems (MRTSs) can cause trains to stop between stations, leading to service disruption and urgent passenger evacuation requirements. Onboard emergency self‐traction systems (ESTSs) can mitigate this risk by enabling a stranded train to reach the nearest station at low speed.

A Practical Optimisation Strategy for Transmission Line Tower Spotting Considering Terrain Features

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
1. Propose a terrain‐feature‐based candidate point selection method to reduce the search space in complex terrain. 2. Develop a full‐process optimisation strategy that decouples tower spotting and tower height adjustment. 3. Validate the proposed method through a real‐world large‐scale transmission line project.
