Abstract：The door system of subway vehicles fails frequently，which afects vehicle operation. Taking the built-in electric door of DKZ15 electric passenger car as the research object，this paper puts forward the analysis method of door subsystem function，failure mode，failure cause and influencing factors based on RCM theory through statistical analysis offailuredata，sorts out allpossible factors and weak links that lead to the failure of this type of door，formulates improvement measures and optimizes maintenance mode，and provides data support for further failure diagnosis and maintenance strategy optimization.The practical data proves that this method can efectively reduce the failure rate of electric passenger door system，reduce the input cost of spare parts，and provide a guarantee for the safe operation of trains.At present，this reliability analysis method of vehicle components has been popularized and used in electric passenger cars on many Beijing metro lines.

Key words： electric passenger car; door system; failure analysis； maintenance strategy; safe operation
