BEHAVIOUR OF PANTOGRAPHS AND THE OVERHEAD EQUIPMENT AT SPEEDS HIGHER THAN 160 KM/H. THEORETICAL STUDIES AND TENTATIVE TESTS CONDUCTED BY BR (DYNAMIC BEHAVIOUR)

BR has conducted tests in order to develop a method leading to a better knowledge of the behaviour of the overhead equipment at high speeds and enabling the parameters, playing a predominant part in the physical system, to be represented in a convenient way. The method which has been used in the studies is the method of the finite difference of Abbott of the Royal Aircraft Establishment. The mathematical model has been developed so as to represent simple catenary equipment and the solution of the equations is performed at short, consecutive time intervals, using a computer, The validity of the results obtained from the mathematical model was checked by comparision with the results obtained from the line tests. Though there are numerous other variations of the parameters which could form the subject of detailed studies, it has been possible to draw useful conclusions and to compile recommendations from the study described in this report.
