| Abstract: | According to the actual situation of the EMU operation and maintenance, with the purpose of predicting the remaining useful life for EMU the key components, this paper studied on the train-ground data of EMU. The features of temperature data of traction motor bearing were extracted. The remaining useful life of the bearing was predicted according to the large amount of EMU history data. The idea of process oriented analysis and the method of constructing box graphs with feature extract were used to achieve the purpose of remaining life prediction of EMU traction motor bearing. The results of the study could be used as the basis for improving operation and maintenance efficiency. |
