| 摘 要： | 在现场条件下，用随机减量技术从运行机械中提取出对轴承转子系统稳定性敏感的模态参数（系统的最低阶自然频率和阻尼比），用这些参数对系统的失稳实施监测，实际应用的结果表明，用这种方法可以及早地发现系统潜在的失稳．

| Abstract: | By applying the random decrement technology to rotating machine on site to substract the modal parameters(Lowest natural frequency and damping factor), which are very sensitive to rotor instability. The above parameters is thus used for rotor instability analysis. The practical experiments verify that this methods can discover the rotor instability in early stage. |
