摘要

以 C01 型电主轴轴承-转子系统为研究对象，建立了轴承-转子系统的动态模型，展示了电主轴在高速运转时的动态特性。提出了利用动力流分析电主轴振动特性的方法，发现在振动位移响应显著的位置，振动能量并不一定很大。最后，分析了不同轴承刚度下的系统振动能量分布。功率流方法可以从能量分布的角度分析轴承-转子系统的动态特性。

Research on vibration characteristics of motorized spindle at high speed based on power flow

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.
