Bearing Fault Diagnosis Based on Spatial Features of 2.5 Dimensional Sound Field
The traditional acoustic-based diagnosis (ABD) technique based on single-channel testing has a significant engineering value. Since its diagnosis robustness is sensitive to sound signal acquisition location, it develops slowly. To solve this problem, the 2-dimensional (2D) sound field variation near...
