摘要
讨论了转子一滑动轴承复合系统中，各轴承及转子的稳定性对其复合系统的稳定性的影响和作用问题。运用大系统稳定性的理论和方法，为各滑动轴承和转子子系统及其集结系统引入了反映其各自稳定性状态的“广义能量”──李雅普诺夫函数。并在此基础上首次导出并定义了各子系统对其集结系统的灵敏度，用以刻划它们对复合的转子一轴承系统运动稳定性的影响大小。给出了实例以验证定义的正确性和方法的实际应用。
The stability sensitivity analvsis is presented for rotor-sliding bearing systems . By applying the stabiliy theory on the system, a kind of generalized energy--Liapunov function was introduced to reflect the stability sta- tus of bearing and rotor subsystems and their aggregated system . Based on that the stability index is defined and de- duced which is used to describe the influences of the bearings and the rotor to the stability of their compound sys- tem . Some examples are given to show the correctness of the difinition and the success of the approach as well as its uniqueness compared with some other sensitivity analysis methods .
