Air braking is the main form of braking for freight trains. With the rapid development of heavy-duty freight trains, the running speed of trains continues to increase, and the number of train formations and axle loads are constantly increasing. In order to cope with more complex brake environments, the braking system needs to further study the error in controlling train air pressure and methods to improve control accuracy. This article establishes a model of the entire vehicle air braking system based on AMESIM. Based on the different braking stages of freight trains as the theoretical basis, the train pipe constant pressure, air temperature, brake system pipe lengths, and air distribution valve parts parameters can be adjusted to obtain a model that is more in line with the actual situation. In addition, this paper confirms the accuracy of this model through mutual verification with brake tests.
