Abstract: Commonly, the method of air braking combined with electric regenerative braking was used for high-speed train to control the train speed or stop the train to a standstill. This method was belong to adhesive braking. The braking effect was affected by wheel/rail adhesion coefficient. With the increase of train speed, the coefficient was on a declining cure, the probability of wheel sliding was increased. So the anti-skid control was of significance. This article analyzed the problems of CRH2 EMU trains’ applications, put forward the plan which could optimize the anti-skid control method, reduced the faults of Anti-skid Control System effectively.
