FENet: A Physics‐Informed Dynamics Prediction Model of Pantograph‐Catenary Systems in Electric Railway

IET Intelligent Transport Systems, Volume 19, Issue 1, January/December 2025.
In this manuscript, we proposed physics‐informed surrogate model, called FENet, for the first time to solve the interaction of pantograph‐catenary system. In recent years, much progress has been achieved in PCS modelling solutions. Existing solutions, however, suffer from two significant limitations: 1) An urgent concern arises regarding the ...

Risk Mapping for Daily High‐Speed Railway Disturbances Based on Operation Loss

Journal of Advanced Transportation, Volume 2025, Issue 1, 2025.
Confronted with the disturbances arising from various risk events, it is crucial to accurately measure the severity of risks in the dispatching section for efficient train operation and transportation management of a high‐speed railway (HSR). This paper proposes a risk mapping method for daily HSR disturbances based on a self‐formulated operation loss ...

Defect Diagnosis of Rigid Catenary System Based on Pantograph Vibration Performance

Actuators
The condition of a catenary is significant to ensure a high current collection quality. Owing to the dynamic interaction between the pantograph and the catenary system, the vibration of the pantograph can be used to analyze the condition of the catenary ...
