Abstract

When an electric multiple units (EMU) runs on a long heavy downgrade track, electric brake failure may occur during the anti-skid control process, which would result to longer pneumatic braking time, high brake pad temperature and wear, etc. Thus, it is important to determine optimal strategies for the anti-skid control of EMUs through field experiments. In the present study, a method of spraying anti-friction fluid was adopted to simulate rail surface conditions with low adhesion. This would allow low adhesion conditions and enable the EMU to continuously operate on it. Then, control parameters and strategies were constantly adjusted to obtain the optimal glide. The field experiment revealed that it is feasible to reduce electric brake failure times and improve electric power flow by optimizing the anti-skid control strategy.
