Research on Pressure Characteristics of Vehicle Air Braking System with Leakage from Pipeline

Based on the vehicle air braking system circuit analysis, a pressure characteristics model in the states of normalcy and leakage was built, and the relationship between brake pressure characteristics and leakage was studied. Based on the modeling and study, simulation was done using the MATLAB; On the other hand, experimental setup of vehicle air braking system was designed, and the experiments were carried. Then the simulation results were compared with experimental results. By comparison and analysis, we come to a conclusion that the model in this paper can accurately describe the pressure characteristics of vehicle air braking system.
