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.

Active Control of Contact Force for a Pantograph-Catenary System [PDF]
Shock and Vibration, 2016 The performance of the high speed trains depends critically on the quality of the contact in the pantograph-catenary interaction. Maintaining a constant contact force needs taking special measures and one of the methods is to utilize active control to ...

Simulation and Verification of Effect of Arc Duration on Arc Temperature Based on COMSOL
Machines, 2023 The pantograph–catenary arc of urban rail has the characteristic of high temperature, which directly acts on the surface of the pantograph–catenary system, will seriously ablate pantograph and contact line, and affect the flow of the pantograph–catenary ...

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 ...

Effects of Crosswind on Pantograph–Catenary Wear Using Nonlinear Multibody System Dynamic Algorithms
World Electric Vehicle Journal, 2023 In this study, a multibody system (MBS) computational framework is developed to determine the exact location of the contact point and wear prediction resulting from the pantograph–catenary interaction. The railroad vehicle models in the MBS computational
