Study on the dynamic behavior of the pantograph and its infuence on current collection

- Abstract
- The study of the dynamic interaction between pantograph and catenary by computer simulation is useful as it allows us to obtain much information about this system while minimizing the cost of line tests. With a program validated by the norm EN 50318, the behaviour of a pantograph-catenary couple at a certain speed can be accurately estimated. With the program INPAC, a parametric study on the current collection quality with the criteria given in EN 50367 was lead. The aim is to have a better understanding of the influence some parameters have on current collection quality and if trends or general rules for the impact they have can be found.
The parameters studied were computation parameters and physical parameters. The study of the first...

The aim is to have a better understanding of the influence some parameters have on current collection quality and if trends or general rules for the impact they have can be found.
The parameters studied were computation parameters and physical parameters. The study of the first type of parameters also allowed us to evaluate the robustness of the program. In the physical parameters the parameters were those related to the catenary model, to the pantograph model but also the speed and distance between the pantographs when multiple pantographs were used.
The influence of the chosen parameters was isolated, and, in most cases, the trends of the influence of those parameters were found. The robustness of the program used for the simulations was also evaluated and the numerical parameters were adjusted to have more accurate simulations but also to optimize the computation time of the simulations. The influence of some physical parameters from the catenary or the pantograph has also been extracted from the data. The influence of each of the parameters is discussed in this document and areas for improvement, either for simulations methods or conception of the system, are suggested. (Less)
