Pombo, (Editor), "Proceedings of the Second International Conference on Railway Technology: Research, Development and Maintenance", Civil-Comp Press, Stirlingshire, UK, Paper 141, 2014. doi:10.4203/ccp.104.141

Keywords: catenary, pantograph, overlap span, finite element method, current collection, contact force, contact wire tension, span length.

Summary

When a pantograph runs to the overlap span of the catenary, the contact force of the pantograph-catenary and the uplift of the pantograph will have a greater change as the pantograph touches the double contact wires when running at high speed. This especially happens to the rear pantograph, when the double-pantograph runs, producing much worse conditions for current collection. Firstly, a Euler-Bernoulli flexible beam catenary model and a three-mass-block pantograph model are established using the MSC.Marc software adopting: the finite element method, and the solutions of the pantograph-catenary coupling dynamic differential equations are obtained using the Houbolt numerical integration method. Secondly, the current collecting performance of the four-span insulated overlap span when the contact wire tension and span length happen to change is discussed. The current collecting characteristic is analyzed and contrasted when the singer-pantograph and doublepantograph are used. The influence of the design parameters on the change in current collection performance is obtained by analyzing the results of the calculations.
