摘要
介绍了用子结构传递矩阵法计算大型汽轮发电机组基础-轴系耦合振动.利用该法可以在IBM-PC机上方便地计算轴系-轴承-基础组成的复杂系统的转子临界转速、基础固有频率、振型和不平衡激振力的响应.
A calculation method of coupled vibration of large turbine-generator rotor strings including foundation with substructure transfer matrices is presented. By using this method, the rotor's critical speeds, the foundation's nuture frequencies and unbalance responses of complicated rotor-bearing-foundation system may be calculated conveniently on a IBM-PC computer.
