Research on Hydrodynamic Characteristics of Six-leaf Dislocated Floating-ring Bearing

The characteristics of the radical-thrust hybrid floating-ring bearing considering inertia term were studied as the rotor-bearing is working with high rotary speed.

The results show that the boundary element method has unique superiority for calculating the hydrodynamic characteristics of the complex shape floating-ring bearing.

The hydrodynamic characteristics of lubricant in six-leaves columniform floating-ring bearings were studied by means of boundary element method,the distribution of flow field in six-leaves columniform floating-ring bearings and the distribution of pressure on the surface of bearings and outer floating-ring were obtained.

The discrete element method was introduced into the dynamic model of floating ring bearing rotor system for the first time and the dynamics simulation program of floating ring bearing rotor system was developed.

Based on two experiments on floating ring bearing before and after floating ring thickness re-duction,the effect of thickness variation of floating ring on whirl and stability was studied.

Based on two experiments on floating ring bearing with different floating ring thickness,the effect of variation of thickness of floating ring on whirl and stability was studied.
