Abstract

A tool to calculate mechanical forces on railway catenary J. Benet, F. Cuartero & T. Rojo Escuela Politecnica Superior, Univ. de Castilla-La Mancha Campus, Spain Abstract We will present the basis for the mechanical calculation of the catenary sys- tem in a railway, considering static wire equations. Our objective is to allow an increment in the speed in railways, by developing an accurate mechanical calculation of the electric wiring known as catenary. Also two algorithms for the calculation are developed. In the first one, the exact weight of the wire is considered, while in the other, the weight of the wire is estimated as a uniform horizontal load. Finally, this algorithm will be used to implement a software tool. 1 Introduction The evolution in the transport market resulting from the globalization of the economy, the increasing deregulation of the markets, the competition on the base of a customer service, the growing environmental concerns, and the need to ensure a long
