A Numerical Solution of the Dynamic Characteristics of an Aerostatic,Porous Thrust Bearing Having a Uniform Film Subjected to Linear Axial Load Variations

Abstract

A numerical method of solution is presented for the pressure distribution in the uniform air film of a porous thrust bearing in which the top plate is subjected to vertical vibrational motion. From this pressure distribution it is possible to compute the bearing's dynamic characteristics, the knowledge of which is essential for the design of these bearings if unstable operating regions are to be avoided.
