Current Status and Development Trends of Research on Condition Monitoring of Aeroengine Spindle Bearings (III)

Current Status and Development Trends of Research on Condition Monitoring of Aeroengine Spindle Bearings (III)

The information fusion method is actually a simulation of the comprehensive processing of complex problems by the human brain. In a multi-sensor system, the information provided by various sensors may have different characteristics. By fully utilizing multiple sensor resources in space and time, various observation information is reasonably controlled and used, and redundant and complementary information is combined according to certain criteria, resulting in a consistent description of the observation object and a new fusion effect. Based on the independent observation information of each sensor, by optimizing the combination of information, more effective information is derived, ultimately improving the effectiveness of the entire system. The signal fault characteristics of spindle bearings are weak and the background noise is strong, and information fusion methods have good advantages in processing this type of signal.
