doi:10.3901/JME.2025.11.167

Abstract

Abstract: The simulation model of the heavy-haul train air brake system is too complex to simulate slowly. In order to solve the problem, fast simulation method has been proposed. First, in the AMESim software, a simplified model is created based on the pressure characteristics of the 120-1 air brake valve. Secondly, the simulation model of air brake system established by parallel method is compared with the simulation model of air brake system established by traditional method. The simulation results show that the simulation time of the parallel method is at least 50% less than that of the traditional method. The longer the train formation is, the more complex the model is, the more obvious the simulation acceleration effect of the parallel method is, and the simulation time is reduced by up to 94%. Finally, the air brake system model of 20 000 tons heavy haul train is established by parallel method. The simulation results are compared with the test results to verify the accuracy of the simulation model. The single valve model is simplified and the air brake system model is established by parallel method, which reduces the state variables of the air brake system model of the heavy haul train and improves the simulation speed. It provides a new fast simulation method for the air brake system of the heavy haul train.
