BEHAVIOUR OF PANTOGRAPHS AND THE OVERHEAD EQUIPMENT AT SPEEDS HIGHER THAN 160 KM/H. THEORETICAL INVESTIGATIONS AND EXPERIMENTAL TESTS BY BR (STATIC BEHAVIOUR)

BR have carried out a programme to develop methods for theoretical analysis of the static behaviour of the overhead contact system. Methods have been obtained, and computer programmes written, for calculation of static geometry and of static uplift characteristics. The results obtained are compared with those obtained from measurements made on test equipment. The report also contains a theoretical analysis of the oscillations of the overhead contact system and the results of this study are compared with experimental results. The way in which these results can be used in analysing the dynamic performance of the current collection system is considered, and finally an indication is given of the way in which BR are developing more complete theoretical methods for this dynamic analysis.
