摘　　要：利用Ｒｉｃｃａｔｉ传递矩阵方法，计算分析了某２００ ＭＷ汽轮机轴系的不平衡响应。研究表明，接长轴是轴系中对不平衡较为敏感的部位，在接长轴加重可以得到较好的轴系平衡效果。In this paper, the unbalance vibration of a 200MW steam turbine rotor system is calculated by use of Riccati transfer matrix method. A conclusion is drown that joint shaft rotor is very sensitive to unbalance in the rotor system. A Perfect balancing can be gained by adding correction mass on the joint shaft.
