- Abstract
The air supply system of metro train mainly includes air source system, air cylinder and air equipment and pipeline components, which plays a vital role in ensuring the normal operation of air equipment and ensuring the safety, stability and comfort of vehicles. The traditional design and selection of air supply system are estimated according to typical working conditions based on experience. In this paper, the AMESim analysis software is used to establish pneumatic simulation models of air spring suspension system(including air spring, height adjustment valve and pressure adjustment valve) and brake system according to the working principle of each component in the air supply system. Moreover, the performance simulation analysis platform of train air supply system with various formations can be built according to the air supply schematic diagram of standard metro train. Based on this platform, in addition to the analysis and calculation of the initial air charging condition of the train, the working state of the air supply system can also be analyzed according to the changes of the passenger capacity of the vehicle when it stops and the partial load of the air spring when it negotiates the curved line combined with the actual running line, such as the start and stop times and average working rate of the air compressor in the air source system, the pressure changes of the air cylinder and the air spring. At the same time, the air consumption of each air equipment can be monitored, so as to evaluate the comprehensive performance of the train air supply system. The platform is of great engineering significance for improving the capability of air supply system performance design and analysis and reducing its energy consumption.
