摘要
在用实测到的支承动刚度计算大型汽轮发电机转子的临界转速中,会出现一些反常现象,进行现场实测时也发现有类似情形。本文分析了产生这一现象的相本原因,指出了实测支承动刚度的重要性和必要性。
When we calculate critical speed of large turbogenerator rotor using measured support dynamic stiffnesses, some non-normal phenomena are shown and some similar phenomena are discovered in the measurements on site. This paper analyzed principal cause for the phenomena and showed importance and necessary of measuring support dynamic stiffnesses.
