摘要

针对列车受电弓振动控制方法进行研究。针对二元受电弓模型,建立基于牛顿第二定律的动力学方程。采用磁流变阻尼器对弓网接触力波动进行控制。采用变论域模糊控制器作为控制算法。仿真研究结果表明:随着列车运行速度的提高,弓网接触力波动越明显,研究的受电弓振动控制方法相比传统的模糊控制以及被动控制方法作用下接触力不平均系数明显降低。将磁流变阻尼器安装于上框架与弓头之间工况相比安装于框架底座与下框架之间时,接触力不平均系数有所降低,弓网接触力波动更低。

Abstract

In this paper, the vibration control method of train pantograph is studied. A dynamic equation based on Newton’s second law is established for the two element pantograph model. Magneto rheological damper is used to control the contact force fluctuation of pantograph catenary. A variable universe fuzzy controller is adopted as the control algorithm. The simulation results show that with the increase of train speed, contact force fluctuation is more obvious, this paper studies the power control method of arch vibration compared with the traditional fuzzy control and passive control method under the action of the contact force is not the average coefficient. When the magneto rheological damper is installed between the upper frame and the bow head, the contact force between the frame and the lower frame is lower than that of the lower frame, and the contact force of the pantograph catenary fluctuates less.
