With the return period, the remaining service life for bearings 1_3 in the vertical direction is less than one month, for bearings 1_5 in the horizontal direction and for bearings 1_7 in the horizontal direction is more than 25 years. Structure of CNN. As for accuracy, it is assessed by computing the cumulative relative accuracy (CRA) of the RUL prediction results for the selected bearings in PRONOSTIA dataset , and the RUL of the tested bearings in PRONOSTIA dataset is computed according to predicted failure age and actual failure age of bearing, like the instance presented in Section 3.2. Remaining Useful Life (RUL) estimation of rotating machinery … Signals is an international, peer-reviewed, open access journal on signals and signal processing published quarterly online by MDPI.. Open Access — free to download, share, and reuse content. To explain, traditional approaches used to resolve prognostic problems may lack appropriate models, which are capable of considering complex dynamics of combined faults, which result in degraded performance. 26 implemented an adaptive DCNN for the Case Western’s bearing data set 27 to perform fault diagnosis. Predicting bearing degradation before reaching the state of risk of accident is one important issues in power generation insurance. The time series data of bearing operation are divided into multiple channels to be fed into the convolutional neural network (CNN) to extract relationship between far apart data points. To evaluate the proposed approach, two public multi-sensor data sets are used for the remaining useful life prediction applications: (1) CMAPSS turbofan engine dataset, and (2) FEMTO Pronostia rolling element bearing data set. There are two popular data sets, the Intelligent Machine Systems (IMS) NASA and the PRONOSTIA dataset. Bearings are widely used in rotating machinery, and their prognostic and health management (PHM) is crucial to the precision and reliability of mechanical systems [1,2,3].As a significant aspect of the prognostics method, remaining useful life (RUL) estimation contributes significantly to the PHM of bearings [].Typical bearing RUL estimation methods primarily … loading) is found or if several training data sets are available in each bearing problem.
