The creep phenomenon will inevitably occur in the course of railway vehicles traveling. By solving the creep mathematical model, the relationship among wheel-railway adhesion coefficient, vehicle speed and creep rate is obtained. On this basis, the mathematical model of ABS and AMESim simulation model are established, and the simulation and analysis are completed under the conditions of track drying and wetting. The temperature field of disc brake is analyzed based on ABAQUS. The boundary condition of finite element model is defined and the load is consistent with the simulation result of AMESim. The research shows that the anti-lock braking system (ABS) has a good application effect, which can keep the vehicle braking in the optimal creep state, reduce the braking distance and time, and improve the anti-thermal attenuation ability of the brake disc. The application of anti-lock braking function in hydraulic braking system is of great significance to the improvement of railway vehicle transportation capacity.
