摘要：
Dynamic current collection of the pantograph-catenary system turns out to be one of the key technologies for high-speed railways. Speed limitations have to be accepted when an electric multiple unit (EMU) runs with two pantographs. In this paper, the analytical solution to dynamic current collection of the pantograph-catenary system is calculated and the dynamic pantograph-catenary interaction is analysized, where the infinite string model is used for the catenary system and the lumped mass model for the pantographs. The catenary sag, suspension stiffness and propagation and the influence of carbody vibration on the vertical displacement of contact wires and pantograph slippers are obtained for high-speed railways in our country. The pantograph-catenary parameters for the high-speed railways at a running speed of 200 km/h in Russia are calculated to verify the correctness of the approach. The optimal distance between two pantographs and the influence of the reduction mass of the pantograph on current collection of the pantograph-catenary system are studied. The study provides theoretical reference for optimization of pantograph parameters.
