Popis: Based on the Navier-Stokes equations in which the pressure is assumed to be constant across the film thickness, various approximate solutions for the static and dynamic performances of an infinitely wide, plane inclined slider pad in a laminar flow regime are presented under the assumption of a small harmonic vibration. From comparison of the approximate solutions with the numerical one, it is concluded that one kind of averaging approach in which some of the time dependent terms are treated exactly while the convective inertia terms are averaged out across the film thickness gives close approximations in a wide range of desigining conditions, and that an other kind of averaging approach in which all the inertia terms including the time dependent terms are averaged out across the film thickness is a fairly good approximation.
