Abstracts:
In urban rail transit industry ， DK - 2 brake is gradually introduced into electric engineering vehicles. The brake has the functions of network communication，hybrid braking and intelligent closed -loop precise control，which can effectively guarantee the high speed，safety and punctuality of metro engineering vehicles. The application of DK-2 brake on metro engineering vehicle is introduced，and various braking modes and main control principles of the brake are analyzed. Combined with the experience of Guangzhou metro engineering vehicle，several common fault phenomena of DK -2 brake are put forward. Fault analysis ideas and fault determination methods are expounded，and troubleshooting suggestions are provided for overhaulers and drivers to improve the locomotive fault handling efficiency，ensuring the safety of operation.
