摘要

通过激振实验获得磁悬浮轴承转子系统的动态特性参数

并与实际运行状态进行比较。结果表明

激振实验能够获得系统在高速旋转状态下的稳定性、临界转速及其与控制参数间的关系。另一方面

激振实验结果表明

某些临界转速值对控制参数的灵敏度很小

无法通过改变控制参数

改变这些临界转速值。

Abstract

Dynamic characteristics of turbine magnetic bearing system by excitation test are studied in this paper.The method can be useful for prediction of critical speeds

stiffness and damping of the system

before it goes into operation.On the other hand

excitation test shows that adjustment of control parameters has less influence on some critical speeds.
