ABSTRACT
To show dynamic properties of a motorized spindle at high speed, C01 type motorized spindle
bearing-rotor system is used as a study object, and the dynamic model of the bearing-rotor
system is established. The method to analyze vibration characteristics of motorized spindles
by power flow is proposed, and it is found that the vibration energy is not necessarily
considerable at the position where the vibration displacement response is significant. Finally,
the system vibration energy distribution under different bearing stiffness is analyzed. The
power flow method can analyze the dynamic characteristics of the bearing-rotor system in
terms of energy distribution.
