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.

Hough transform and thermo-vision for monitoring pantograph-catenary system
Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, 2006 The pantograph-overhead contact wire system is investigated by using an infrared camera. As the pantograph has a vertical motion because of the non-uniform elasticity of the catenary, in order to detect the temperature along the strip from a sequence of infrared images, a segment-tracking algorithm, based on the Hough transformation, has been employed.

Contact force control in multibody pantograph/catenary systems
Proceedings of the Institution of Mechanical Engineers, Part K: Journal of Multi-body Dynamics, 2016 In this paper, a new continuum-based pantograph/catenary model based on the absolute nodal coordinate formulation (ANCF) is proposed and used to develop an effective method to control the contact force which arises from the pantograph/catenary interaction.

An Interactive Model of a Pantograph-Catenary System
Vehicle System Dynamics, 1996 SUMMARY The overhead electrification system for high speed trains is modeled by a three degree of freedom pantograph and an infinite homogeneous and elastically supported beam. Travelling wave solutions for the beam with a moving load are used to derive an equivalent stiffness for the pantograph model.

Dynamics of the Pantograph-Catenary System
, 2019 Pantograph-catenary interaction is a critical issue for electrified railway systems, as it represents a limiting factor for the maximum speed at which the electric rolling stock can be operated and, at the same time, strongly affects the reliability, availability and maintainability of both the rolling stock and the infrastructure.

Moving horizon control and estimation of a Pantograph-Catenary system
2013 17th International Conference on System Theory, Control and Computing (ICSTCC), 2013 This paper deals with the moving horizon estimation and predictive control synthesis of a Pantograph-Catenary (PAC) system. The pantograph is the element of the train that collects electric current from the overhead line, the catenary. At high speeds, the contact between the pantograph and the catenary becomes less and less consistent resulting in poor

A spatial coupling model to study dynamic performance of pantograph-catenary with vehicle-track excitation [PDF]
Mechanical Systems and Signal Processing, 2021 In the high-speed railway industry, the pantograph-catenary system is responsible to provide continuous electric energy for the highspeed train. The pantograph-catenary system suffers multiple impacts from the complex work environment.

A tracking control for pantograph-catenary system
2015 54th IEEE Conference on Decision and Control (CDC), 2015One of the relevant problems in high-speed train transportation systems is the regulation of the contact force between the catenary and the pantograph. The contact force should ensure a satisfactory permanent electricity feeding for the train. In this paper, a linear time varying (LTV) model of the pantograph-catenary (PAC) system is introduced.
