Engineering StructuresThe rigid catenary is an important component in transmitting electricity to the trains operating in underground tunnels. Stability of the contact force is one of the key indicators of reliable power transmission, which is directly influenced by the vibration response of the catenary.

Effects of Crosswind on Pantograph–Catenary Wear Using Nonlinear Multibody System Dynamic Algorithms
World Electric Vehicle Journal, 2023 In this study, a multibody system (MBS) computational framework is developed to determine the exact location of the contact point and wear prediction resulting from the pantograph–catenary interaction. The railroad vehicle models in the MBS computational
