摘要
本文用有限单元法分析汽轮发电机组轴系扭转振动问题,并编制了相应的计算程序——STAP程序。利用此程序计算和分析了轴系结构参数和轴系扭转振动固有频率之间的关系。最后给出了国产某300MW汽轮发电机组轴系扭转振动的固有频率。
The natural frequencies of torsional vibrations of the turbogenerator shaft Series are calculated with the Finite Element Method (FEM) and the correspouding computer program, STAP, is worked out. By making use of this program, the relation-ship between the natural frequencies of torsional vibrations and the structural parameters of the shaft series are calculated and analysed. As an example, the natural frequencies of torsional vibrations of a 300MW turbogeneator shaft series are given.
