Research on Oil Synthetic Analytical Techniques and Information Fusion for Aeroengine Fault Diagnosis

摘要：

Aeroengine fault took considerable proportion in airplane faults, so the techniques of condition monitoring and fault diagnosis of aeroengine had become the research focuses recently. Aeroengine wear was studied by oil synthetic analytical techniques and information fusion method of Dempster-shafer Evidence Theory. First, oil analytical techniques such as spectrographic oil analysis, ferrographic oil analysis, infrared spectrographic oil analysis, routine physical and chemical oil analysis were studied in detail. Secondly, the relationship between aeroengine wear fault and information of oil analysis were systematically summarized. Finally, Dempster-shafer Evidence Theory applied to oil analysis is studied. These techniques above would have better development prospects for applying to aeroengine wear fault diagnosis.
