摘要
介绍了采用多段集中质量模型计算轴系扭振特性的两种方法：传递矩阵法及特征向量法。并利用上述两方法对某电厂１ 号机轴系的扭振特性进行了计算分析。
In this paper, transfer matrix method and eigenvector method are introduced to calculate the torsional vibration characteristics of steam turbine generator rotor system with discrete model. The natural frequencies and mode shapes of a 200MW turbine generator rotor system are calculated with the two methods.
