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 simulation 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 threedimensional 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. When the train speed reaches 250 km/h, the additional uplift force caused by the high speed air flow on pantograph is about 12 N and the drag force is about 550 N.
