| Abstract: | In this paper, Several dynamical eguilibrium problems for suberitical rotational speed
of turbogenerator-unit rotor are discussed. It emphatically pointed out that thec bending ri-
gidity direction of horizental rotor is the main reason ofr causing suberitical rotational
speed, besides, it also gives the stable criterion of Viberation caused by subcritical rotational
speed. |

| Keywords: | subcritical rotational speed rotor Viberation stability |
