Wavelet Analysis of Misalignment Fault of Rotor-Bearing Systems

摘要

A misalignment rotor-bearing systems is studied as an object.Comparing two kinds of vibration characteristics of 0 torque excitation and linear torque excitation.The experimental data are analyzed by FFT and wavelet.Conclusion is obtained.Certain torque excitation can control oil whirl to a certain extent.On the other hand,linear torque excitation can increase degree of misalignment.
