Method and data processing device for severity assessment of bearing defects using vibration energy

摘要: Method for detecting bearing defect severity based on rotation speed and at least one data sample of sensor obtained to measure vibrations a ring is provided. The method includes converting the from time domain frequency obtain signal spectrum; determining center using speed; identifying predetermined number peaks spectrum. A total vibration energy in an overall band including first determined; next, each peaks, peak as spectral components giving rise calculating energies; finally ratio assess obtained.
