TL;DR: In this article, the influence of misalignment of geometrical parameters on static and dynamic characteristics of hybrid bearings in laminar and turbulent flow regimes is presented, and experimental results and numerical results obtained with two numerical procedures.
Abstract: The analysis of actual lubrication problems needs to take into account particularities in flow caused by kinematic conditions and contact geometry. For hybrid journal bearings lubricated by low dynamic viscosity fluid, turbulence and pressure drops due to inertia forces in the recess outlets are phenomena which must be taken into account to compute their working characteristics. These bearings serve as both vertical and horizontal shaft guides particularly under low speed conditions. They are used in mechanisms which are highly loaded at start-up and which cannot generate hydrodynamic load-carrying capacities at low speeds. They avoid damage because of their stabilizing effects, but cannot conceptually cope with shaft misalignment. In this paper, the influence of misalignment of geometrical parameters on static and dynamic characteristics of hybrid bearings in laminar and turbulent flow regimes is presented. Experimental results and numerical results obtained with two numerical procedures, i.e., the finit...

TL;DR: In this paper, a theoretical study of the characteristics of a multipad plane hydrostatic thrust bearing was made taking into account the effect of rotational lubricant inertia, and design data for the load capacity, flow and stiffness and damping characteristics were obtained for practically useful radius and resistance ratios for capillary and orifice compensation.
