Abstract
The present disclosure provides a method for predicting a remaining useful life (RUL) of an aero-engine, specifically including: acquiring multidimensional degradation parameters of an aero-engine to be predicted to obtain acquired data; segmenting the acquired data by a sliding window (SW) to obtain preprocessed data; constructing a RUL prediction model of the aero-engine including a multibranch convolutional neural network (MBCNN) model, a multicellular bidirectional long short-term memory (MCBLSTM) model, a fully connected (FC) layer FC1, and a regression layer; taking the preprocessed data as input data of the MBCNN model, extracting an output of the MBCNN model, taking the output of the MBCNN model and recursive data as input data of the MCBLSTM model, and extracting an output of the MCBLSTM model; obtaining an output of the FC layer FC1, and inputting the output of the FC layer FC1 to the regression layer to predict a RUL.
