STATIC AND DYNAMIC BEHAVIOR OF A FLEXIBLE BASE FLUID SUSPENSION

The object of the thesis is to uncover a set of analytical expressions which will adequately permit the design of a flexible base air bearing and to verify these expressions experimentally. Simplifying assumptions include adiabatic flow through the inlet orifices and in the plenum beneath the diaphragm. Bending and shear stresses in the diaphragm are assumed to be negligible compared to tensile stresses. In the steady-state analysis, an equation is developed which predicts the platform height as a function of plenum pressure and also yields the bearing float limit condition. By averaging and linearizing, a limited amount of dynamic theory is developed which yields the bearing stability limit and completes the analysis. Experimental correlation of the theory is presented as well as a Fortran computer program which performs the necessary computations. (Author)
