摘要
首次运用大系统稳定性理论及方法研究大型转子－滑动轴承系统的稳定性问题。着重于刻划转子。轴承系统稳定性的定性性能及方法学；定义、引入并解释了描述系统稳定性的性能指标及其物理意义；探讨解决机械系统目前常用的一些传统稳定性分析方法难以解决的问题。文中给出的实例表明了方法的可行性、有效性和独到之处，论文的直接应用背景是大型汽轮发电机组轴系的稳定性问题。
The paper discusses for the first time the stability issues of Complex Rotor-Shding Bea-ring Systems by the Stability Theory of Large-Scale Dynamic Systems。 The emphases areplaced on the qualitative aspects of the system’ s stability , as well as on the methodology ofthe approach.Some performance indices of the stability for the system are defined and intro-duced,and their physical meanings explained. The purpose of the paper is intended to exploitsome important aspects of system' s stability behaviour,which are supposed to be difficult toaccess to by some classical methods, The illustration example is given to show its validity anduniqueness.
