| 摘 要： | 为了探讨调节系统对汽轮发电机扭振的影响，从调节系统角度建立了在将轴系按质量弹簧系统处理时的数学模型，从简单物理模型开始，求得了考虑扭振特性后轴系的频率特性，并且得到了一些概念上比较清楚的结论。在这个基础上将它推广到普遍的情况—多质量弹簧系统。并给出了多质量弹簧系统的一个计算实例。

| Abstract: | As to research the influence of control system on the turbo-generator shaft torsional oscillation, in this paper the mathematical model of the turbo-generator shaft system from the point of view of automatic control is given. The discussion begins from a simple physical model, the frequency characteristic of the shaft system is given in considering with the torsional oscillation, and some basic problems and conclusions are discussed. On these bases the mathematical model of a multi mass-spring shaft system is introduced too. At the end of this paper the calculation results of a multi mass-spring shaft system are given. |
