Abstract :
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.
