大容量汽轮机—发电机轴系振动的研究与探讨

Investigation and Discussion of the Shafting Vibration of Large Steam Turbine-generator

本文就汽轮机—发电机轴系振动问题提出了如何解决的方法。其中就轴系的动态稳定性、转子的热变形对轴系振动的影响加以论述,并用200MW机组的典型例子加以说明、分析。最后,就振动增大的主要两大因素加以简单的总结。

This paper presented the methods how to solive the problems of shafting vibration of steam turbine- generator. The above methods include the influences of shafting dynamic stability and thermal defermation of rotor on shafting vibration and explanation using an example for 200MW set. Finally, the main factors of the increase in ribration amplitude were be discussed.
