This paper presents recent developments undertaken by SNCF Innovation & Research Department on numerical modelling of pantograph catenary interaction. It aims at describing an efficient co-simulation process between Finite Element (FE) and Multibody (MB) modelling methods. FE catenary models are coupled with a full flexible MB representation with pneumatic actuation of pantograph. These advanced functionalities allow new kind of numerical analyses such as dynamic improvements based on innovative pneumatic suspensions or assessment of crash risks crossing areas that demonstrate the powerful capabilities of this computing approach.

Communication avec acte(Civil-Comp Press, 2016)Fatigue cracks can induce fracture of the catenary Contact Wire (CW) and thus huge costs for the operator. Nowadays the wear criterion to replace the CW leads to lifespan over than 50 years, and the catenary can see a very ...
