| 摘 要： | 本文用三质量模型分析汽轮发电机组轴系扭转振动问题,建立机组轴系扭转振动的分析模型。以研究机组轴系在发电机、励磁机的激振扭矩作用下的扭转振动特性为例,得到了模型的幅频特性曲线和响应的表达式。同时还得到了短路冲击作用下,轴系的扭转角响应和各轴段(联轴器)上扭矩响应的解析解。

| Abstract: | The three-mass-model system of the vibration of a turbogenerator shaft is presented and used to analyze the turbine generator shafts torsional vibrations The Ampltude-Frequency character of the three-mass-model system is obtained when the excitations came from the generator or exciter. Under the actions of short-circuits in the network or power station, the response of the shaft torsional torques and angles of the turbine generator are presented. |
