Through the numerical solution of the unsteady Reynolds equation of turbulent lubrication, the dynamic characteristic coefficient of the water-lubricated guide bearing was studied. On this basis, the bearing-rotor system was simply simplified and corresponding differential equations of motion were established. Based on this equation, the stability of the bearing is calculated and analyzed, the stability conditions are given, the reasons for the instability of the lubrication die are analyzed, and the corresponding suggestions for improving the bearing design are put forward.
