Yang, Hongyu, Mathew, Joseph, Ma, Lin, & Kosse, Vladis (2004) Matching pursuit feature based neural network pattern recognition of ball bearing faults. In International Conference of Maintenance Societies 2004, 25-28 May 2004, Sydney, Australia.
The task of condition monitoring and fault diagnosis of rotating machinery faults is significant but is often cumbersome and labour intensive. Automating the procedure of feature extraction, fault detection and identification of rotating machinery has the advantage of reducing the reliance on experienced personnel with expert knowledge. Rolling element bearing failure is one of the foremost causes of breakdown in rotating machinery. This paper proposes a schema to automate the diagnostic procedure based on a newly developed time frequency analysis technique -Matching Pursuit. Features are extracted based on Matching Pursuit analysis and subsequently input to a Feedforward Neural Network (FFNN) to classify bearing conditions including Healthy, Inner Race Fault (IRF), Outer Race Fault (ORF), and Rolling Element Fault (REF). The performance of the automatic diagnostic procedure was then evaluated using classification rate and Mean Square Error (MSE). The proposed procedure successfully classified the four conditions of rolling bearings.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
