Simulation of High-Speed Pantograph Dynamic Performance Based on Finite Element Model and Aerodynamic Pantograph Model

A coupled finite element model for the pantograph-catenary system and an aerodynamic pantograph model were built. Based on the models, the dynamic current collection and aerodynamic performances of the pantograph were studied using MSC-Marc and STAR-CD simulations of software. In the finite element model, the pantograph and catenary subsystems are integrated into a whole system through contact coupling between them to simulate the dynamic behavior of the pantograph-catenary system. Then, the aerodynamic performance of the high-speed pantograph was simulated on the three-Dimensional aerodynamic pantograph model. The simulation results show that the dynamic uplift and average contact force of simple suspension are smaller than those of stitched suspension.
