Abstract

The presence of environmental noise and multi-source vibration complicates the extraction of features and the localization of faults in vibration-based fault detection. To accurately detect and locate faults this paper introduces a novel methodology that leverages the power of the improved adaptive multiscale morphological filter (IAMMF) algorithm in conjunction with the refined composite multiscale fluctuation dispersion entropy (RCMFDE) algorithm to identify the various health conditions of the bearing. The proposed method first employs IAMMF to filter the signal, thereby eliminating the noise and harmonic interference components and enhancing the fault characteristics. Subsequently, features are extracted from the vibration signals with enhanced fault characteristics using RCMFDE. Experimental results demonstrate that the proposed methodology exhibits exceptional diagnostic and generalization performance. Comparative analyses with several existing methods underscore the advantages of this approach. This research provides a new idea for feature enhancement and location in fault detection.

期刊介绍： Since its launch in 1968, Applied Acoustics has been publishing high quality research papers providing state-of-the-art coverage of research findings for engineers and scientists involved in applications of acoustics in the widest sense. Applied Acoustics looks not only at recent developments in the understanding of acoustics but also at ways of exploiting that understanding. The Journal aims to encourage the exchange of practical experience through publication and in so doing creates a fund of technological information that can be used for solving related problems. The presentation of information in graphical or tabular form is especially encouraged. If a report of a mathematical development is a necessary part of a paper it is important to ensure that it is there only as an integral part of a practical solution to a problem and is supported by data. Applied Acoustics encourages the exchange of practical experience in the following ways: • Complete Papers • Short Technical Notes • Review Articles; and thereby provides a wealth of technological information that can be used to solve related problems. Manuscripts that address all fields of applications of acoustics ranging from medicine and NDT to the environment and buildings are welcome.
