UNIFORMLY ELASTIC OVERHEAD CONTACT WIRES FOR HIGH-SPEED ELECTRIC RAILWAYS

GLEICHMAESSIG ELASTISCHE FAHRLEITUNGEN ELEKTRISCHER BAHNEN FUER HOHE GESCHWINDIGKEITEN

Ordinary catenary structures are, owing to the suspension of the contact wire and the carrying cable, very unevenly elastic when the upward contact force of the pantograph moves as travelling load along the wire. At high speeds this produces large dynamic forces. Only the partial smoothing effect of the tensioned contact wire makes the present train speeds possible. The article reviews the theoretical possibilities for obtaining a static uniformly elastic contact wire and also indicates how the effects of practical influences, such as friction in the bracket joints, etc., which act against this objective, can be eliminated.
