Dynamic Analysis of Pantograph-Catenary System considering Ice Coating [PDF]
Shock and Vibration, 2020 Ice coating on overhead contact system (OCS) will affect the sliding of pantograph, and arc discharge phenomena will occur between pantograph and catenary, which will threaten the normal operation of train.

Backstepping Controller Design for Pantograph-Catenary System [PDF]
IOP Conference Series: Materials Science and Engineering, 2018 This paper proposes an active control method to suppress the contact force fluctuation between pantograph and catenary for high-speed trains with external disturbance. First, fitted by using the non-linear least square method, stiffness of catenary is applied to the Pantograph-Catenary system(PCS).

Dynamically substructured testing of railway pantograph/catenary systems [PDF]
Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, 2018 This paper presents a methodology for testing railway pantograph/catenary systems based upon the dynamically substructured system approach for combined physical and numerical components, originally developed by Stoten and Hyde. The main advantage of the dynamically substructured system is that it can provide more stable substructured testing than ...
