| Abstract: | 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. |
