Influence of Track Irregularities in the Catenary-Pantograph Dynamic Interaction [PDF]

, 2020
This paper presents an advanced pantograph-catenary-vehicle-track model, which allows us to analyze the vertical dynamics of the complete system. The developed model is able to evaluate the displacements and the contact force generated in the catenary ...

Pantograph-Catenary System Modeling Using MATLAB-Simulink Algorithms [PDF]

Contacts 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.

An investigation into multi-domain simulation for a pantographcatenary system

ITM Web of Conferences, 2017
There is a need for modelling various phenomena present in a pantograph-catenary structure, (e.g. wave propagation and its reflections, friction, aerodynamic and electromagnetic forces), which allows for a more reliable study on the dynamic behaviours of

Pantograph-catenary interaction in curved railway tracks [PDF]

, 2019
An approach for the dynamic analysis of pantograph-catenary interaction in curved tracks or in any generalized track trajectory is presented here. Both the catenary model and the trajectory path of the pantograph are consistent with the general geometry,

Pantograph–Catenary Interaction Prediction Model Based on SCSA-RBF Network

Applied Sciences
As a traditional numerical simulation method for pantograph–catenary interaction research, the pantograph–catenary finite element model cannot be applied to the real-time monitoring of pantograph–catenary contact force, and the computational cost ...
