Simulation Research of Anti-sliding Control of Urban Rail Brake System based on AMESim and Simulink

摘要

Anti-sliding control of urban rail brake can effectively improve the adhesion utilization rate of the train, shorten braking distance and prevent wheel scratches. This paper takes differential velocity plus slip rate and speed reduction plus its differential as slip criterion, using logic threshold control method to establish Single wheel anti-slip control system. Pneumatic model, mechanical model and control model are built in AMESim and Simulink to implement co-simulation. Simulation results show that the comprehensive model can effectively achieve the anti-slide function. And by taking wheel glide distance as evaluation index, the merits of the two kinds of antiskid criterion are analyzed. The results show that deceleration and deceleration differential criterion as sliding criterion effect is better.
