\r\ncatenary\/pantograph interface for a train in motion. A 2.5D

\r\ncomplex model of the pantograph strip has been defined and created

\r\nby a coupling between a 1D and a 2D model. Experimental and

\r\nsimulation results are presented and with a comparison allow

\r\nvalidating the 2.5D model. Some physical phenomena are described

\r\nand presented with the help of the model such as the stagger

\r\nmotion thermal effect, particular heats and the effect of the material

\r\ncharacteristics. Finally it is possible to predict the critical thermal

\r\nconfiguration during a train trip.","references":"[1] JD Anderson Jr. Transformations and Grids. Springer, 2009.\r\n[2] M. Braunovic, V. Konchits, and N. K. Myshkin.
