Given the harsh operating conditions and complex structure of the turbofan engine, it is extremely difficult to establish an accurate physical model for remaining useful life (RUL) prediction. The traditional operation and maintenance method based on the physical model has several limitations in the application of turbofan engines, while the data-driven method offers a new solution. Compared with traditional machine learning models, deep learning models possess more powerful nonlinear expression capabilities and feature extraction capabilities. Therefore, this study focuses on studying the RUL prediction algorithm for turbofan engines based on the fused deep learning models. In this article, a multimodal deep learning approach based on a 1DCNN (1D convolutional neural network) + attention enhanced Bi-LSTM (bidirectional long short-term memory) network is proposed to predict the RUL by mining the temporal information of data. Furthermore, a DDResNet (dilated deep residual network) is also introduced to the 1DCNN submodel to leverage its hidden pattern mining capability due to its advance in preventing performance degradation across layers. Subsequently, the output of these two submodels is weighted fused to obtain the final RUL prediction. The merits of the proposed method are demonstrated by comparing it with existing methods for RUL prediction using the C-MAPSS (commercial modular aero-propulsion system simulation) dataset.<\/jats:p>","DOI":"10.1115\/1.4054090","type":"journal-article","created":{"date-parts":[[2022,3,15]],"date-time":"2022-03-15T08:35:12Z","timestamp":1647333312000},"update-policy":"https:\/\/doi.org\/10.1115\/crossmarkpolicy-asme","source":"Crossref","is-referenced-by-count":8,"title":["Prediction of Remaining Useful Life Using Fused Deep Learning Models: A Case Study of Turbofan Engines"],"prefix":"10.1115","volume":"22","author":[{"given":"Yu","family":"Zheng","sequence":"first","affiliation":[{"name":"School of Mechanical Engineering, Shanghai Jiao Tong University, Shanghai 200240, China"}]},{"given":"Xiangyu","family":"Bao","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, Shanghai Jiao Tong University, Shanghai 200240, China"}]},{"given":"Fei","family":"Zhao","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, Shanghai Jiao Tong University, Shanghai 200240, China"}]},{"given":"Chong","family":"Chen","sequence":"additional","affiliation":[{"name":"Guangdong Provincial Key Laboratory, of Cyber-Physical System, Guangdong University of Technology, Guangzhou 510006, China"}]},{"given":"Ying","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Engineering, Cardiff University, Cardiff CF24 3AA, UK"}]},{"given":"Bo","family":"Sun","sequence":"additional","affiliation":[{"name":"Shanghai Electric Gas Turbine Company Limited, Shanghai 200240, China"}]},{"given":"Haotong","family":"Wang","sequence":"additional","affiliation":[{"name":"Shanghai Electric Gas Turbine Company Limited, Shanghai 200240, China"}]}],"member":"33","published-online":{"date-parts":[[2022,3,31]]},"reference":[{"issue":"2","key":"2022033114001964200_CIT0001","doi-asserted-by":"publisher","first-page":"418","DOI":"10.3390\/s21020418","article-title":"A Remaining Useful Life Prognosis of Turbofan Engine Using Temporal and Spatial Feature Fusion","volume":"21","author":"Peng","year":"2021","journal-title":"Sensors"},{"key":"2022033114001964200_CIT0002","doi-asserted-by":"publisher","first-page":"1","DOI":"10.1109\/TIM.2021.3059500","article-title":"Feature Extraction for Data-Driven Remaining Useful Life Prediction of Rolling Bearings","volume":"70","author":"Zhao","year":"2021","journal-title":"IEEE Trans.
