This paper deals with unstable and/or forced vibrations of an asymmetrical rotor driven through a universal joint. As a result of the approximations for unstable vibrations, the number, position and width of the unstable regions change markedly with rotor asymmetry, angular velocity fluctuation of a driven shaft and the effect of gyroscopic action of a rotor. The unstable regions obtained from the approximations coincide well with the results obtained by the numerical integration of the equations of motion. For forced vibrations, an unbalance of the rotor and a secondary moment of a universal joint cause vibrations with the frequencies of odd multiples and even multiples of the drive shaft rotation, respectively. The analytical results for forced vibration are confirmed experimentally.
