Introduction of variability in pantograph-catenary dynamic simulations [PDF]
, 2013 Currently, pantograph-catenary dynamic simulations codes are mainly based on deterministic approaches. However, the contact force between catenary and pantograph depends on many key parameters that are not always quantified precisely.

Pantograph-Catenary System Modeling Using MATLAB-Simulink Algorithms
Scientific Journal of Riga Technical University. Computer Sciences, 2010 Pantograph-Catenary System Modeling Using MATLAB-Simulink AlgorithmsContacts between pantograph and catenary are the most critical parts in the transmission of electrical energy for modern high-speed trains. Contact wire oscillations change combined force between pantograph and catenary, and the contact may even get lost.

Statistical identification of geometric parameters for high speed train catenary [PDF]
, 2014 Pantograph/catenary interaction is known to be strongly dependent on the static geometry of the catenary, this research thus seeks to build a statistical model of this geometry.

A Fast Simulation Model of Pantograph–Stitched-Catenary Interaction in Long-Distance Travel
Applied SciencesThe increasing operation speed of high-speed trains allows the pantograph to continuously interact with the catenary over a long distance in a short time, and many new methods have been developed to efficiently calculate its dynamics.
