BEHAVIOR OF PANTOGRAPHS AND OVERHEAD CONTACT SYSTEMS AT HIGH SPEEDS. CHARACTERISTIC DATA ON THE DYNAMIC BEHAVIOUR OF PANTOGRAPHS AND OVERHEAD CONTACT SYSTEM
This report chiefly represents a summary of all the results, conclusions and recommendations that have emanated from the work done by the A3 Specialists Committee. The report refers especially to the characteristic data on the dynamic behaviour of pantographs and overhead contact systems. For this purpose a compilation of recommended design principles and data which offer a basis for further developments has been included. The report has been established after another analysis of all the results of the preceding series of tests, supplemented by investigations of a theoretical nature. Furthermore, additional measurements on overhead contact systems have, for the purpose of this report, been made by the OBB, DB and NS. The progress of the investigations has been rendered more difficult by the fact that it did not prove possible to determine, separately, the influence of each parameter affecting design and construction. This is due to the complexity of the designs and the large number of parameters involved. Despite all this, the report contains much advice of a practical nature pertaining to the design of the most important component parts. It is, moreover, explained in the report in what manner the complex movements of pantographs and overhead contact systems may be divided and analysed. As regards such investigations, forces, masses and elasticities are rather important. The report shows how these and other characteristic data on the dynamic behaviour have been measured. Furthermore, measured and calculated characteristic data are compared with each other. The principal object of these investigations has been to use the results of the tests as a basis for determining, by means of calculation, the combined action of pantograph and overhead contact system and also for determining beforehand, the behaviour of future designs. So far, this has only partly been achieved. The last chapter of the report contains a summary of characteristic data and recommendations for use in practice.
