摘要：
The oil film force produced by hydrodynamic journal bearing is a kind of highly nonlinear force. The hydrodynamic bearing-rotor system is a typical nonlinear dynamic system. Using linear stability theory, the motion after loss of stability can not be obtained. In this paper, a method of transient numerical simulation to simulate and analyze the nonlinear vibration of rotor-bearing system is presented. Using this method, the motion after loss of stability of an elliptic bearing-rigid rotor system is calculated and analyzed in detail.
