Pneumatic Exhaust Calculation and Tests for Metro Vehicle

In order to design pneumatic brake system of the Metro vehicle,this paper presented useful method "pneumatic exhaust calculation" and taked GZL28 projects for example.In order to choose the right compressors,the air consumption of the vehicle must be determined.After choosing the compressors,the charging time of the vehicle and the demanded number of emergency brake applications in case of total compressor failure were calculated.Finally the design was confirmed by site tests.
