Abstract

Abstract

In order to improve the vertical dynamics performance of pantograph for high-speed train, the nonlinear vertical dynamics model of pantograph, the vertical finite element dynamics model of catenary and the dynamics model of vehicle were set up.Pantograph-catenary coupled vibration and track irregularity excitation were taken into account, the displacement and velocity of the top point of pantograph frame or pantograph head were taken as feedback control signals, and active control actuator or semi-active control damper was mounted between the base and the frame of pantograph.The numerical simulation method was used to study the semi-active and active controls of pantograph-catenary vertical coupled vibrations, and the control effects were compared.Comparing with passive system, the standard deviation of pantograph-catenary contact force decreases at least 26.84% when train speed is 250 km·h^-1, and decreases at least 20.88% when train speed is 300 km·h^-1.So pantograph-catenary vibrations and contact force fluctuation at low frequencies are reduced evidently by using semi-active and active controls, current collection quality is improved, semi-active control is simple and easy to realize, and it will not affect the original dynamics performance of pantograph even if the control is disabled.
