Nonlinear Transient Stability of Cylindrical Fluid Film Journal Bearing with an Axial Groove

Lintu Roy

Abstract


The investigation deals with non-linear stability analysis of two cylindrical fluid film bearings having an axial groove, one fed at constant pressure from the top and another fed from the bottom separately. Graphical results are presented for the stability boundaries of rigid rotor supported on two identical bearing configurations. The lubricant is assumed to be isoviscous. It has been found that a bearing fed from the top is much stable in comparison to that of fed from the bottom under unidirectional constant load also a bearing found to be a stable one may be made unstable by superimposing a periodic load on the system.
