ON THE NUMERICAL-ANALYSIS TO THE THERMOELASTOHYDRODYNAMIC LUBRICATIONOF A TILTING-PAD INCLUSIVE OF SIDE LEAKAGE

Numerical solutions are obtained for the thermoelastohydrodynamic lubr ication of a tilting pad based on the three-dimensional flow of lubric ant. For elastic deformation, the pad is idealized as a uniform plate with free boundaries so that a displacement coefficient matrix can be established by the conventional finite difference method. For pressure distribution, a fast Newton-Raphson's approach is used in solving the generalized Reynolds equation, film thickness equation, inlet pressur e buildup equation, and the force balance and moment balance equations of the pad, simultaneously. For temperature distribution, the finite difference method is carried out with the help of a sweeping scheme.
