结合上海轨道交通11号线南端三轨受流器结构，分析下部受流方式的受流器系统与三轨端部弯头接触时的垂向振动特性。在Matlab/Simulink中建立受流器系统与三轨端部弯头的接触模型，并建立地铁车辆整车Simpack模型，将整车模型中构架的垂向振动与受流器系统垂向振动耦合，分析当地铁车辆运行速度提升后，影响受流器系统的垂向振动特性的因素，从而通过改变受流器系统相关刚度，增加一定的阻尼以及改变三轨端部弯头坡度等参数，使之满足提速要求。

This paper analyzed the contact characteristics between metro vehicle collector shoe and third rail which was based on the collector shoe structure of Shanghai metro line 11 southern vehicle. It mainly explored the influence factors of the collector shoe vertical vibration characteristics after speeding up. The framework and the current collection mode were coupled when the Simulink contact model of collector shoe with the third rail ends and the Simpack model of the metro vehicle were established. It maintains that by changing the stiff-ness of the collector shoe,inclination of the contact rail ends,adding a certain amount of damping and changing the suspension stiffness,the requirements for speeding can be met.
