ABSTRACT.
THIS PAPER PRESENTS A BOUNDARY ELEMENT ANALYSIS OF THE CONTACT MECHANICS BETWEEN STEEL BEARINGS WITH DIFFERENT CERAMIC COATINGS AND THICKNESSES. THE PHYSICAL CONTACT BETWEEN THE SPHERICAL BEARINGS, AND BETWEEN THE BEARINGS AND OTHER COMPONENTS, MAKES THE PROBLEM GEOMETRICALLY NONLINEAR SUCH THAT AN ITERATIVE PROCEDURE OF SOLUTION IS REQUIRED. AN EFFICIENT AXISYMMETRIC BEM FORMULATION HAS BEEN DEVELOPED FOR THIS PURPOSE WHICH INCORPORATES FEATURES SUCH AS SUBREGION MODELLING AND A FAST ITERATIVE SOLVER.
KEYWORDS: BOUNDARY ELEMENT METHOD, AXISYMMETRY, CONTACT. |
