Stiffness and damping characteristics of conical multirecess hybrid journal bearing for different load arrangements

Abstract

This paper presents the theoretical analysis on the effect of two different load arrangements for a conical multirecess hybrid journal bearing. For this analysis constant flow valve restrictors are used under micropolar lubricant for different semi cone angles. The modified Reynolds equation using micropolar fluid flow on the conical surface has been solved with the use of FEM and Galerkin’s technique applying proper boundary conditions in the iterative scheme. The study suggests that the configuration LA I can be a better alternative as compared to LA II for different semi-cone angles and external load in terms of bearing characteristics.
