文摘

Numerical results are presented for three fully dynamical lubrication devices (piston ring–liner, journal bearing and mechanical seals) based on the Elrod–Adams model for the Reynolds equation and Newmark scheme for the motion equations. For each lubricated system we give the mathematical model, the corresponding non-dimensional problem and numerical results. We give also the full algorithm in the case of the piston-ring–liner system.
