Research on the Dynamic Response of the Catenary of the Co-Located Railway for Conventional/High Speed Trains in High-Wind Area

Infrastructures
To establish a theoretical foundation for assessing the dynamic performance of high-speed train catenary systems in wind-prone regions, this study develops a coupled pantograph–catenary model using ANSYS(2022R1) APDL.

Aerodynamic Shape Design of Pantograph Network Monitoring Device on High-Speed Trains

Journal of Applied Fluid Mechanics, 2019
The pantograph monitoring device on high-speed trains bears not only its own strength but also the aerodynamic load applied by the air flow when the train is running at high speed.
