This research project studies the effect of wind gusts on the interaction between catenary and pantograph by means of 3D simulation models. On the one hand, the aerodynamic effect of the wind on catenaries and pantographs of high speed trains is studied applying both new numerical models and the results measured with an aerodynamic channel, which were obtained within the previous project EVITAV. On the other hand, the project developes numerical 3D models catenaries and pantographs able to include the numerical and experimental aerodynamic information.
The main goal of this project is transcending the current catenary-pantograph simulation models by adding the effect of the wind over this dynamic interaction and the clear upgrade that 3D formulations entail. This study is tackled by comparing the numerical results obtained both with simplified models and complex models of catenaries and pantographs of high speed trains. It is specially valuable the benefits reported by the advanced 3D models against the classical 2D ones developed within previous projects.
The numerical study is carried out by the Institute for Research in Technology of Universidad Pontificia Comillas (IIT-COMILLAS). Besides its small size, this research group has reached important contributions to the catenary-pantograph simulation problem and has become one of the most internationally relevant groups of reference. This project wides the objectives of the research line opened within the last National Plan, moreover it generalizes and overcomes the limitations of the developed 2D models.
