Abstract
A numerical procedure is developed for the analysis of transient thermoelastohydrodynamic (TEHD) behavior of connecting-rod bearings under dynamic loading. The Reynolds and energy equations in the film and heat transfer equation in the solids are all solved using the Newton-Raphson method and the finite element formulation. The finite element meshes of the three domains are interconnected, and so the heat flux continuity conditions become implicit. As a consequence, the study of complicated structures, such as actual connecting-rod bearings, can be handled and boundary conditions can easily be changed. [S0742-4787(00)02301-8]
