Reconstruction of angular speed variations in the angular domain to diagnose and quantify taper roller bearing outer race fault
Mechanical Systems and Signal Processing(2019)
摘要
•Basic analyses exhibit shape of speed fluctuations for healthy and faulty bearings.•Changes due to operating conditions and size of the defect are clearly separated.•The method can be applied in non-stationary operating conditions.•BPOO changes explained as modification in bearing kinematics are shown and analyzed.
