摘要
本文介绍了大型汽轮发电机组定子端部绕组的固有振动分析的一种高效方法，即扇区分析法。文章由两分组成：首先从理论上扼要说明这一方法的思想和原理，然后把它应用到工程实际中──３０万千瓦汽轮发电机组定子汽端的实例分析。文末列出一系列图表，结果显示了扇区分析方法的优越性。
A dynamic analysis technique for the free vibration of generator'S end-winding is presented. The whole paper is composed of two parts. First, it briefly describes the property of rotationally periodical structure and the sector analysis method. Then, to illustrate the use of the above method, its application to the calculation of the nomal modes for three-hundred-thousand-watt turbogenerator's end-winding with inner water-cooled stator and rotor is given.
