Performance characteristics of an externally pressurized capillary-compensated flexible journal bearing

Finite element analysis of orifice-compensated multiple hole-entry worn hybrid journal bearing

“…Eq. (18) gives the corrections in the values of nodal pressures in the current iteration, e.g., for mth iteration, { p 0 } m . The new nodal pressures for the next (m + 1)th iteration is obtained as…”

“…(23) are expanded by Taylor series about the ith journal center position and the increments ( X i j , Z i j ) on the journal coordinates are obtained as given below [15,18]:…”

Effect of Elasticity on Capillary Compensated Flexible Multi-recess Hydrostatic Journal Bearing Operating with Micropolar Lubricant

“…The lubricant flow rate Q R through capillary restrictor neglecting gravitational force, in non-dimensional form is given as [15]:…”

“…For Newtonian lubricant, Sinhasan et al analytically studied the effect of bearing shell flexibility on the performance characteristics of hydrostatic journal bearing using capillary [15], constant flow valve [16] and orifice flow restrictors [17]. They presented that with Newtonian lubricant for heavily loaded journal bearings, the elastic deformation of the bearing shell due to fluid-film pressures is of the order of magnitude of fluid film thickness.…”

Static and Dynamic Performance Characteristics of Orifice Compensated Hydrostatic Flexible Journal Bearings with Non-Newtonian Lubricants

“…Thus, over the past few decades many investigations dealing with hydrostatichybrid journal bearings have been carried out and reported in the literature ( I ) , (2), (9)- (12).…”
