dcterms:description
The modeling of the roller bearing brings two important problems. The contact problem means that two surfaces touch one another. The contact transmits the pressure force but not tensile force. It is not known neither the contact area nor the distribution of the contact pressure. The second problem is the largeness of the structure, the number of degrees of freedom (DOF). Nowadays the hardware allows solving the large systems of equations. Nevertheless if the number of DOF goes over 105 or 106 and the algorithm necessitates the iterative approach this could be the problem. The effective way of solution can be domain decomposition using so called super-elements. The paper brings the description of modeling with super-elements and solving the contact problem.
