A Simplified Mass Conserving Algorithm for Journal Bearing under Large Dynamic Loads

Received16 Mar 1999
Revised27 Aug 1999


A simplified mass conserving solution approach, consisting of analytical and numerical methods, for performance evaluation of dynamically loaded journal bearings is presented. The analytical technique is used to determine position and velocity of journal center for given force components. Subsequently a finite difference formulation of universal Reynolds equation is used to calculate realistic oil flow. The proposed formulation is applied for analysis of an engine main bearing. The entry and exit flow and maximum pressure in the bearing are determined over complete cycle and matched with published results obtained by numerical scheme. The suggested hybrid computational method typically takes 55 s on ICL DRS 6000, and 29 s on 150 MHz Pentium-Pro computer.
