Multiple Pantograph Interaction With Catenaries in High-Speed Trains

Journal of Computational and Nonlinear Dynamics, 2012
The limitation on the top velocity of high-speed trains concerns the ability to supply the proper amount of energy required to run the engines through the catenary-pantograph interface. Due to the loss of contact, not only the energy supply is interrupted, but also arching between the collector bow of the pantograph and the contact wire of the catenary

Influence of the Aerodynamic Forces on the Pantograph-Catenary System for High Speed Trains

Civil-Comp Proceedings, 2009
Most of the high-speed trains in operation today have the electrical power supply delivered through the pantograph-catenary system. The understanding of the dynamics of this system is fundamental since it contributes to decrease the number of incidents related to these components, to reduce the maintenance and to improve interoperability.

Multi-parameter joint optimization for double-strip high-speed pantographs to improve pantograph-catenary interaction quality

Acta Mechanica Sinica/Lixue Xuebao, 2022
The significant increase in speed of high-speed train will cause the dynamic contact force of the pantograph-catenary system to fluctuate more severely, which poses a challenge to the study of the pantograph-catenary relationship and the design of high ...

Effects of Crosswind on the Aerodynamic Characteristics of High-speed Pantograph

2021 IEEE 24th International Conference on Computer Supported Cooperative Work in Design (CSCWD), 2021
Nowadays, electric traction is applied in highspeed trains, and the effects of crosswind increase the instability of the pantograph turbulence, so higher requirements are put forward for the good contact between pantograph and catenary. A new type of pantograph of working height of 2800 mm and a running speed of 400 km/h was taken as the object in this

Active Control of a High-Speed Pantograph

Journal of Dynamic Systems, Measurement, and Control, 1997
The design and performance of an active controller for a pantograph which collects current for a high-speed train are considered. A dynamic model of the pantograph/catenary system is described and control objectives are established. A design which incorporates a frame-actuated controller and requires only a single measurement is described.
