N2 - The pantograph-catenary system, used for collecting electric energy in high-speed trains should ideally run with low contact forces but without contact loss. Not only defects on the overhead equipment, environmental conditions become more important as the operational speed increases but also the flexibility of the pantograph components may play a role on the overhead contact. In this work a flexible multibody methodology using of the mean-axis conditions, as reference conditions, the mode component synthesis, to reduce the number of generalized coordinates of the system and virtual bodies, to allow using all kinematic joints available for multibody modeling and application of external forces, are used to build flexible multibody pantograph models. The catenary model is build with linear finite elements in a stand-alone code, which is co-simulated with the multibody code to represent the complete system interaction, and the complete nonlinear dynamics of the overhead equipment. A flexible multibody model of the pantograph is described and proposed being the quality of the pantograph-catenary contact analyzed and discussed.
