The concentration of the selected 6 elements was used as the monitoring object, and a linear weighted summation process was used to enhance numerical stability of the object value, the monitoring threshold was calculated using the Student distribution model. The computational process needs only the latest 7 \u223c 10 samples, so it is easy to update the monitoring threshold. The method was tested by some samples from aircraft engines and helicopter gear reducers. The test results show that the accuracy of the proposed prediction model is higher than traditional linear model. The proposed monitoring threshold algorithm can forecast wear out failure in advance.<\/jats:p>","DOI":"10.3233\/jcm-204319","type":"journal-article","created":{"date-parts":[[2020,4,14]],"date-time":"2020-04-14T13:36:55Z","timestamp":1586871415000},"page":"1211-1220","source":"Crossref","is-referenced-by-count":2,"title":["Fault
