Abstract:

Aeroengine amalgamates state-of-the-art technologies across diverse domains, serving as a comprehensive manifestation of a nation’s prowess in science and industry. Frequent malfunctions occur due to its complicated structure and harsh service environment. Therefore, it is essential to employ prognostic and health management technology to provide crucial support for aviation safety and reliable operations. As vibration faults constitute a primary failure mode in aeroengine, this paper, grounded in this premise, systematically reviews and analyzes existing vibration monitoring and fault diagnosis for aviation engines both domestically and internationally. The analysis is categorized into three dimensions, covering the application of overall vibration monitoring and diagnostic systems, typical fault characteristics and diagnostic methods, and the overall vibration fault diagnostic technology, including dynamic analysis, signal processing techniques, and relevant technologies such as deep learning. Then, the problems and challenges faced by the existing vibration fault diagnosis of aeroengine are identified. Furthermore, future development goals are provided.

Key words: aeroengine, fault diagnosis, vibration analysis, dynamical model, signal processing, intelligent diagnosis
