摘要
电磁轴承作为一种新颖的高性能支承部件 ,具有传统轴承无可比拟的许多优点 .电磁轴承进入应用基础研究阶段后 ,还有许多实际问题需要解决 ,其中之一就是在高速旋转机器中应用时的转子动力学及其稳定性问题 .此文以电磁轴承支承下的高速转子系统为分析对象 ,研究其动力学特性 .研究的对象是一台 15 0 m3制氧透平膨胀机样机中的电磁轴承转子系统 ,以其三组不同的参数作了临界转速和稳定性计算 .最后 ,分析了观察到的实验现象 ,并与计算结果比较 .
As a new type of supporting component, active magnetic bearing (AMB) has a number of advantages. In its basic research phase for application, many problems still remain to be solved. One problem is safty and stability, namely rotor dynamics as AMB is to be used in high speed machines. This paper presents some experimental results for improvement of the theory and methods used in analyzing the system's dynamic performance. As an example, a 150 m 3 turbo oxygen gas expander was manufactured and tested. The results show good agreement between the theory and the experiment.
