When the rotor accelerated, self-excited vibration generated immediately after passing through the critical speed is treated. Some results of analysis and experiments is described on the relation between maximum angular acceleration and generation of self-excited vibration of rotating shaft system. The main results obtained are as follows; (1) The generation of self-excited vibration and final value of phase difference are mutuality related. The maximum angular acceleration is not affected by unbalance mass and amplitude. (2) Theoretical values of maximum angular acceleration is closely coincident with experimental values. (3) To obtain the higher stability, the external damping coefficient of rotating shaft system has to be increased and the maximum angular acceleration become larger.
