The Effect of Linear Inertia on the Squeeze Film Action Between A Curved Circular Plate and A Flat Plate

Abstract

The effect of linear inertia on the action of the curved squeeze film between two circular plates when the upper plate moves normal to itself and approaches the lower plate with uniform velocity,is studied. Expressions for pressure, load capacity and response time are obtained by using the method of averaged inertia and the regular perturbation method. Pressure, load capacity and response time increase markedly with increasing curvature parameter but only slightly with increasing inertia parameter. Numerical values of the bearing characteristics obtained by the two methods are found to be nearly equal.
