Pantograph/Catenary Contact Force Control
Volume 6: 11th International Conference on Multibody Systems, Nonlinear Dynamics, and Control, 2015 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.

With rising of the running speed of the train, the variation of pantograph–catenary contact force (PCCF) signal increases and the current collection quality between pantograph and catenary becomes worse. In order to explore the ways to optimize the PCCF signal, localization analysis of the value and the change of PCCF signal at the dropper-point are ...

Pantograph-catenary contact force provides the main basis for evaluation of current quality collection; however, the pantograph-catenary contact force is largely affected by the catenary irregularities. To analyze the correlated relationship between catenary irregularities and pantograph-catenary contact force, a method based on nonlinear auto ...

Non-contact detection method for pantograph-catenary contact force based on image processing
Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid TransitThis paper introduces a non-contact method for detecting contact force between pantograph and catenary (PAC), based on image processing and Kalman filter. A non-contact method for detecting contact force of PAC, which only utilizes the vertical displacement of the collector head, is proposed.

Comparison of optical and electrical measurements of the pantograph-catenary contact force
SPIE Proceedings, 2010In railway engineering the monitoring of contact force between pantograph and catenary gives information about the interaction between the two systems and it is useful to check the status of the overhead line. Indeed the failure of the catenary is one of the main causes of out of order problems.
