| Abstract: | This paper analyzes the nonlinear vibration characteristics and stability of a symmetrical rotor of single mass supported on multi-wedge bearings, and studies the cause and danger of the semi-frequency vibration, which may occur between the first critical speed and the stability threshold speed of the system. The proposed calculation method and obtained results in this paper could be referred to in engineering design, calculation and application. |
