| Abstract: | In this paper,bearing-rotor test presented first-order natural frequency,1/2 and 1/3 harmonic oil whip as well as some nonlinearity such as bifurcation and chaos in oil whip.Moreover,the process and mechanism of sub-harmonic oil whip in rotor speed rising and drop was studied.According to the frequency locking of 1/2 and 1/3 harmonic oil whip,double low frequencies and amplitude-frequency bifurcation plots,further questions on bearing-rotor system nonlinear dynamics were presented. |
| Keywords: | bearing-rotor system oil whip experimental research |
