Squeeze bearing is one of a variety of non-contact bearings that uses squeeze-film flow effects in order to support a given load without contact between the bearing and its underlying surfaces.  In the squeeze bearing variants analyzed here, rectangular plate and axisymmetric disk, the oscillation of the film height separating the stationary surface and the surface to be levitated creates a cycle-averaged pressure in the film that is greater than the ambient pressure, creating a levitation force.  The magnitude of this force is of interest to those designing such a bearing, and is therefore an important consideration in the accurate modeling of the squeeze bearing and its constituent fluid-film flow elements.Grid deformation module is used to model the motion of surfaces and the results are compared with analytical solutions.
