摘　　要：铁道列车在运行过程中,存在气囊式受电弓不能根据当下列车运行状况进行弓网接触压力随动调整的问题,从而造成了弓网之间的接触压力过大或者过小,进而引起弓网耦合系统不稳定运行。本论文旨在研究不改变受电弓原有机械结构框架的基础上对受电弓气动控制系统进行基于模糊算法的控制机理改造,首先研究明确了现有受电弓的设计缺陷,而后在此缺陷上加入了基于模糊算法的控制系统,通过MATLAB的仿真建模,该控制系统能够完成对弓网接触压力的实时调整。The stable operation of the pantograph and network coupling system is an important guarantee for the safe operation of trains.In the actual application process of the train,the airbag pantograph based on the electro-pneumatic action mechanism cannot perform the pantograph and network contact pressure according to the operating conditions of the trains and the line environment,which causes the contact pressure between the pantograph and the net to be too large or too small,it then causes the pantograph and net coupling system to operate unstably.The purpose of this thesis is to study the modification of the control mechanism of the pantograph pneumatic control system based on fuzzy algorithm without changing the original mechanical structure of the pantograph.
