The nonlinear dynamics of a bearing-rotor system was studied in this paper. Base on the analysis results,we simulated the orbit of bearing-rotor. When the system is running,the orbit of rotor is related to the press distributing of oil film. In order to simulate the orbit of nonlinear elastic bearing-rotor,we used the usually unlimited long bearing model,and obtained the numerical results. Practical results show that this method is feasible. We also developed a CAD system for simulation and visualization.
