The self-excited vibration of a rotor caused by the internal damping forces active in the nonstationary vibration as it passes through the critical speed is analyzed theoretically and experimentally under the assumption of the linear internal damping forces. Paticularly in the present paper the internal damping is quantitatively derived using the first approximated asymptotic equation and its approximateness is verified experimentally for various external damping conditions compairing with the theoretical solution. Further, an acceleration not causing the self-excited vibration is newly proposed by giving consideration to the nonstationary vibration in the neighbourhood of unstable region.
