Abstract
Takes the high-speed EMU with a speed of more than 400 km as the analysis object to establish two kinds of high-speed EMU dynamic models based on Simpack dynamics software,carries out simulation calculation under different equivalent conicity,primary positioning stiffness and anti-hunting damper damping,and analyzes its influence law on the hunting instability frequency of high-speed EMU.The results show that the hunting instability frequency of the two high-speed EMU models increases with the increase of the equivalent conicity;the hunting instability frequency of the two high-speed EMU models decreases along with the increase of the stiffness of the primary positioning;the hunting instability frequency of the two high-speed EMU models increases with the increase of anti-hunting damper damping;and high-speed EMU with a speed of more than 400 km have a high frequency hunting of 10～11 Hz.关键词
