| Abstract: | The evaluation method of the stability of rotor bearing system to multiple degree of freedom is investigated by means of impacting the system with a pulse to excite it to generate free vibration signals. The result shows that the stability of this kind of rotor bearing system can be evaluated by using free vibration signals generated at the location far from the exciting point and that the damping effect of hydrodynamic oil film within the bearing under limit condition is the major factor to make system operation stable. |
| Keywords: | rotor bearing system correlation analysis free vibration logarithmic attenuation criterion stability |
