초록

High speed rotor test rig was developed for flexible rotor systems which have its bending critical speed at 14000 rpm. In designing the flexible rotor systems, operating speed have to be escaped from the critical speed, due to large vibration. In this paper, dynamic characteristics of the rotor systems were analyzed and compared with test results. And the effect of allison ring damper and rotor balancing were examined both theoretically and experimentally. Finally, the magnitude of vibration was largely reduced at the critical speed.
