Simulation and Experimental Research on Anti-sliding Control of Railway Vehicle Braking

Abstract:

By building up the railway wheelset kinematics model,creep force model,braking force open-loop and closed-loop control model,the simulation method on anti-sliding control of braking system is discussed.Regarding the anti-sliding control unit of electro-magnetic brake system,the pneumatic circuit model and anti-sliding control strategy model are also built up based on the DHSplus software.Co-simulated with MATLAB,the characters and parameters of anti-sliding control unit of electro-magnetic brake system are analyzed.In this work,the hardware and software of an anti-sliding device are designed.Some tests and simulation results show that these models are reasonable and useful to speed up the development and integration of anti-sliding control system.
