The Hydrodynamic Bearing interface can be used for modeling the sliding bearings where oil between the journal/collar and bushing acts as a lubricant. Using this interface, you can obtain the pressure distribution in the oil film by solving the Reynolds equation. This interface provides models for the Journal Bearing, Thrust Bearing, Floating Ring Bearing, and Squeeze-Film Damper. For the journal bearing, built-in models for cylindrical, elliptical, split-halves, multilobe, and tilting pad bearings are available. There is also an option to specify a user-defined initial oil film thickness in the bearing for a type of bearing that is not included in the feature. For a thrust bearing available models are tapered, tilting pad, and user defined.
