|Title:||Conical whirl instability of hybrid porous journal bearings in laminar lubrication regime|
Singh, Satinder Pal
|Abstract:||An analysis of conical whirl instability of an unloaded rigid rotor supported in hybrid porous oil journal bearings in laminar lubrication regime is presented here. The effect of bearing feeding parameter (β), aspect ratio (L/D), ratio of wall thickness to journal radius (H/R) and an isotropy of porous material on stability of rotor bearing system has been investigated. Higher values of β have been found to give better stability in conical whirl mode and higher stability is predicted if porous bush is considered to be isotropic.|
