Cao, "A Compound fault diagnosis for rolling bearings method based on blind source separation and ensemble empirical mode decomposition," PLoS ONE, vol.
The paper puts forward the absolute deviation rank diagnostic approach to broken teeth-pitting composite fault, and it took single broken teeth fault, pitting, and composite broken teeth-pitting fault as the research object, using ADAMS to establish gear teeth broken-pitting compound fault dynamics model and single failure dynamic model.
The composite fault is obtained by combining the broken tooth with the pitting failure, composite failure 1 is the combination of the broken tooth 1 and the pitting corrosion 1, and then the compound fault of different degrees can be obtained by analogy.
According to Figure 7, the peak-peak value of the compound fault increased with the augment of the rotating speed under the same load 1790 N-m, and the amplitude value increased with the augment of the fault degree.
Table 4 is the results of the broken teeth, pitting, and broken teeth-pitting compound fault compared with normal model after classification and treatment, in order to more intuitively analyze each of absolute deviation rank values differences to identify the type of fault.
There are three II rank deviations and one II rank deviation in double frequency amplitude, which are fault sensitive parameters for broken teeth-point erosion compound fault.
The use of decision fusion network will greatly improve the accuracy of fault diagnosis and can compound fault diagnosis effectively.
