Stefano Derosa
About
Stefano is currently a postdoctoral fellow in the Structural Dynamics group at the Department of Structural Engineering, Norwegian University of Science and Technology, NTNU. His main task is to focus, within the broader field of the structural dynamics of railway catenary systems, on the understanding and improving prediction models in local wear of contact lines. The research on wear models is in continuation of his PhD. The prediction of wear in the pantograph-catenary contact will be beneficial in terms of better utilization of existing infrastructure and help in the development of new ones. It is, indeed, especially desirable to consider the possibilities of increasing the speed of the Norwegian network up to 250 km/h while maintaining a system with high levels of robustness and reliability. His research activity includes both numerical analyses and field measurement studies, performed both on the infrastructure and on-board of trains in regular service along the Norwegian rail network.
