Abstract

Simulation of the wear behaviour of high-speed over-head current collection systems K. Becker/ A. Rukwied," W. Zweig,*> U.

The optimisation process is fo- cussed on increasing the life time of high speed overhead contact lines. The dy- namic behaviour of the catenary is calculated numerically and the results are used as an input parameter for lifetime prediction. The wear behaviour is simulated up to train speeds of 350 km/h by using a specially designed wear machine. The wear performance is measured automatically by a completely computer con- trolled data acquisition system under the following conditions: - speeds up to 500 km/h, - traction currents up to 1000 A, - contact forces up to 500 N.
