Summary
In this paper, by building a creep force model, the dynamic model of a single vehicle, anti-sliding control model of the braking system and the model of the pneumatic braking system, a simulation method for an anti-sliding strategy for a single vehicle is analysed for the braking condition. The anti-sliding control strategy of the rail vehicle is mainly studied. The anti-sliding control method based on optimal slip rate identification is then proposed. A co-simulation method was introduced using the professional simulation tools AMESim and Matlab/Simulink. The pneumatic model is built using AMESim and the wheel-rail dynamic model and WSP control model are built using Matlab/Simulink. The slope of the adhesion coefficient and slip rate curve is introduced as the criterion for anti-sliding control. In simulations under different sliding conditions, the recursive least square method with a forgetting factor is applied to calculate the slope of the characteristic curve. Simulation results show that the anti-sliding control method based on optimal slip rate identification can achieve a better anti-sliding effect and the best use of the adhesive force under different sliding conditions.
