Abstract: The consistent transform conditions are proposed that deal
with the lubrication equations for various structures of externally
pressurized gas bearing with slot restrictors. The consistent transform
method can map Reynolds Equations in different coordinates into uniform
equivalent form that makes automated programming possible. During the
discretization procedure, the weighted residual method is adopted that
reduces the second-order partial differential equation to one-order,
which releases the requirement of continuity degree of the interpolation
function while finite element method is adopted. The flow field
parameters, such as load capacity, attitude angle and pressure
distribution, are analyzed for externally pressurized gas bearing with
slot restrictors, even in high speed. Furthermore, the method is
extended to dynamic gas bearings successfully.
