Unstable vibration occurs in the vicinities of the major critical speeds of an asymmetrical shaft system. It also occurs in a wide speed range above the major critical speed of a shaft with a hollow rotor partially filled with liquid. The occurrence of unstable vibrations is a serious problem because the amplitude increases exponentially and the system is destroyed. However, no simple effective means for unstable vibration suppression is known before. Active vibration control is usually complicated and costly. In this paper, we show that the simple method proposed to suppress steady-state vibration utilizing discontinuous spring characteristics is also effective to suppress unstable vibrations. The unstable vibration changes to an almost periodic motion and we can suppress amplitudes to an arbitrary magnitude even in an unstable range. The validity of the proposed method is also verified by experiments.
