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.

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.

Evolution of the electrical contact of dynamic pantograph–catenary system [PDF]
Journal of Modern Transportation, 2016 A good contact between the pantograph and catenary is critically important for the working reliability of electric trains, while the basic understanding on the electrical contact evolution during the pantograph–catenary system working is still ambiguous so far.
