Abstract

The trend towards high power output, high speed and low power loss in engines requires a better understanding of bearing behavior. Research in this area is directed more towards different aspects involved in bearing analysis, rather than providing a comprehensive guideline on design of bearing. The effect here outlines a new inverse design methodology, for the design of oil journal bearings. The Reynolds equation has been solved for pressure (steady-state and perturbed) using finite difference method with successive over relaxation scheme. Using the perturbed pressures it has been possible to compute the four components of stiffness and damping coefficients along with the threshold of oil whirl instability of the bearings. Because of oil whirl, the shaft center shifts away from the static equilibrium position, whirls in an orbit, may ultimately come in contact with the bearing surface, thereby the bearing is likely to fail due to seizure
