A Dynamic Model for the Study and Simulation of the Pantograph–Rigid Catenary Interaction with an Overlapping Span

In this paper, the authors present a mathematical and engineering model to optimally calculate dynamic equation on pantograph–catenary interaction when considering rigid catenary with an overlapping span. The starts from well-known methods adapted special features of catenary. As result, algorithm for integration based explicit is provided. Moreover, algorithm, reliable, efficient, user-friendly software tool called RICATI developed in order approach railway-based companies. results show usefulness application. such as RICATI, check behavior configuration initially established catenary, allowing solutions be obtained problems encountered simulating passage pantograph (or pantographs), not only span but also entire That encourages us continue future works.
