Title
Life Prediction of Self-Locking Nut for Aeroengine Based on Survival Analysis and Bayesian Network
Abstract
The self-locking nut is an advanced fastening part, which can be locked by friction. It has been widely used in the connection of aeroengine system nowadays. The performance and reliability of self-locking nut will directly affect the tightness of various aeroengine components, and play an important role in the operation of aeroengine. In this paper, based on the collected lifetime data of aeroengine self-locking nut, the survival analysis method is introduced to discover the influence of each individual variable on the life of self-locking nut at first. Then, after eliminating the irrelevant variables according to survival analysis, a novel Bayesian network (BN) based life prediction model is established to support the decision making of extending service life and improving system reliability. Finally, by comparing with the general BN model with all variables, the performance of the proposed model is verified, and the applications of the model are also given.
