Nonlinear Dynamic Behavior of a Water-Lubricated Hybrid Bearing-Rotor System

摘要：

　　In this study,the stability analysis is carried out on a water-lubricated hybrid bearings used as the support of a high-speed motorized spindle.A two-dimension finite element method considering turbulence effect has been developed to solve the nonlinear oil film force.This paper mainly studies the influence of the water supply pressure,rotating speed,and unbalance mass on the axis orbit of the rotor-bearing system.The results of the axis orbit indicate that the effect of nonlinear for the hybrid bearing studied in this paper is not obvious,and the bearing-rotor system can run safely and stably at the rotating speed not more than 30000 rpm.
