Remaining useful life, technical health, and life extension
Proceedings of the Institution of Mechanical Engineers, Part O: Journal of Risk and Reliability, 2011 Life extension has for a long time been an important and highly discussed issue in nuclear and aviation industries, and has recently attracted considerable attention in the subsea oil and gas industry. Decision-making related to life extension is a multidisciplinary problem, but it primarily depends on the remaining useful life.

Remaining useful life Prediction of air spring
2019 IEEE International Conference on Prognostics and Health Management (ICPHM), 2019The remaining useful life estimation is an important function of an efficient prognostics and health management (PHM) system and can be used preventively to replace the component with the aim of avoiding a breakdown. The prediction of remaining life time of the air spring as one of the critical component of truck is the main goal of this research.

Remaining Useful Life Estimation for LFP Cells in Second-Life Applications
IEEE Transactions on Instrumentation and Measurement, 2021The increasing deployment of battery storage applications in both grid storage and electric vehicle fields is generating a vast used battery market. These batteries are typically recycled but could be reused in second-life applications. One of the challenges is to obtain an accurate remaining useful life (RUL) estimation algorithm, which determines ...

Calculating Remaining Useful Life of Ships
Offshore Technology Conference, 1992ABSTRACT Recent developments of engineering analysis methods enable useful forecasts of physical life of ship hull structures, piping, and machinery. Economic analyses of the costs of rehabilitation and increasing maintenance costs can demonstrate that the useful life of tankers can be extended many years at ...

Problems of Predicting the Remaining Useful Life
2020 IEEE Conference of Russian Young Researchers in Electrical and Electronic Engineering (EIConRus), 2020As the title implies the article, describes some difficulties that appear during the usage process of any technical equipment. It is spoken in detail about the remaining useful life. Different common ways to estimate are described in short. The author attempt made to analyze the Turbofan Engine Degradation Simulation data set.

Overview of Remaining Useful Life Methodologies
Volume 3: 28th Computers and Information in Engineering Conference, Parts A and B, 2008Nowadays, it is imperative for products to function properly each time they are used. If a product fails during its use, it may have disastrous consequences. Estimating remaining useful life (RUL) of a product is a key to prevent such disasters, improve its reliability, provide security and reduce maintenance and operational cost. Naturally, estimation

Remaining useful life estimation with multiple local similarities
Engineering Applications of Artificial Intelligence, 2020Abstract In prognostics and health management (PHM), remaining useful life (RUL) estimation has become a major focus for guaranteeing the safety and reliability of systems. Similarity-based RUL estimation methods, which predict a system’s RUL based on the RULs of other systems with similar degradation behaviors, have been proven effective when no or ...

A Probabilistic Framework for Remaining Useful Life Prediction of Bearings
IEEE Transactions on Instrumentation and Measurement, 2021This article presents a probabilistic framework for remaining useful life (RUL) prediction of bearings. This framework comprises two phases: 1) early fault detection, i.e., modeling the vibration signal as a series of graphs and then conducting graph spectrum analysis to detect the topological change of graph for early fault detection and 2) RUL ...

Bidirectional handshaking LSTM for remaining useful life prediction
Neurocomputing, 2019Abstract Unpredictable failures and unscheduled maintenance of physical systems increases production resources, produces more harmful waste for the environment, and increases system life cycle costs. Efficient remaining useful life (RUL) estimation can alleviate such an issue.
