城轨列车混合制动防滑控制技术研究

Research on the Antiskid Control Technology for Mixed Braking on Urban Rail Trains

介绍了城轨列车防滑系统的组成及控制原理。针对电空混合制动防滑控制时电制动切除时刻对防滑控制效果和电制动利用的影响,提出了按照滑行程度不同确定电制动切除时刻的方案。

The composition and control principles of the antiskid system on urban rail trains are described.In view of the effect of the time of switching off electric braking in the antiskid control of electropneumatic mixed braking on the antiskid control effect and the electro-pneumatic braking application,the scheme to determine the time of switching off electric braking on the basis of different skid degrees is put forward.
