| 英文摘要: |
| The mathematical model of single degree of freedom (DOF) nonlinear autonomous bearing system under constant flow supporting model is deduced. The single DOF nonlinear autonomous bearing system is transformed with the method of linear and nonlinear treatment, the mathematical expression and parameters sensitivity of relative error of stiffness and damping are presented. Finally, the main factors of magnetic-liquid double suspension bearing (MLDSB) are analyzed, and the influence on bearing performance indicators of single DOF nonlinear autonomous bearing system of main factors is revealed. The results show that linear stiffness/damping is the first part of equivalent stiffness/damping, and the second and third parts are high order minor term of Tayor series transform. The film thickness, the magnetic-liquid proportionality coefficient, the mass of rotor are the major influence factor of the bearing performance. The research can provide the theoretical reference for the design and nonlinear analysis of MLDSB. |
