Abstract:
The structure and operating principle of air braking system for subway train were introduced. The modelling methods of three basic types of pneumatic components including capacitive, resistive and inductive unit were explained. The simulation model of air braking system was built based on the similarity principle and the AMESim. The models and simulation parameters of load valve, EP unit and relay valve were analyzed. The characteristics of brake cylinder and Cv pressures were discussed under service brake, emergency brake and phased brake, and the result was verified by test bench. Analysis result shows that Cv pressure response is faster than the pressure response of brake cylinder in service and emergency brake, the maximum delay is no more than 0.5 s, and the stabilities of both pressures are equal. It takes less than 1.5 s when brake cylinder pressure rises to the constant pressure in emergency brake, and the value is less than 2.2 s in service brake. Regarding phased brake, brake cylinder pressure and Cv pressure follow better. In test, stabile Cv pressure is about 15 kPa higher than brake cylinder pressure because of the damping effect of internal rubber parts of relay valve, but the error does not affect the normal use of relay valve. 1 tab, 9 figs, 15 refs.
