| 摘 要： | 以２００ＭＷ汽轮发电机组为对象，运用模态分析和传递矩阵方法。通过理论分析和对实机的数值计算。研究了轴系的不平衡响应，结果表明，轴系的不平衡响应为各不平衡质量分别产生的呼应的线性叠加；某一不平衡质量容易激起该不平衡振动所在轴段的振型。

| Abstract: | The characteristics of unbalance of turbine generator rotor system are studied by use of modal analysis and Riccati transfer matrix method. The study shows that the superimposition of several lower mode shapes is approximately equal to the superimposition of all the mode shapes. The result shows, when the unbalance is located on a segment of rotor, the mode shapes of this segment and nearby segments are easily excited. The unbalance characteristics of a 200?MW turbine generator rotor system are calculated in this paper. |
