Abstract

In this work, an advanced algorithm for the mechanical calculation of the catenary system in a railway is presented. The main objective is to allow an increment in the speed in railways, by developing an accurate mechanical calculation of the catenary. Among the different types of these kind of electrical systems, the so called stitched catenary presents a better dynamical behaviour, because it maintains a more uniform stiffness along the span. Of course, the price to be paid consists of a greater complexity due to the existence of two kinds of carriers, the main and the secondary ones. Finally, the presented algorithm will be used to implement a software tool.
