Abstract

The stress-strain state of a spherical contact unit with a layer of antifriction polymer material is investigated within the framework of the problem of elastoplastic contact interaction with the account of friction on the contact surface. The statement of the problem of contact mechanical interaction of two elastic bodies through an elastoplastic layer of antifriction polymer material is made. The contact characteristics at different finite element meshes are investigated, optimal mesh parameters for numerical modeling are chosen and convergence of numerical solution of the problem is established by the example of axisymmetric problem. As a result, numerical studies have established the influence of the geometry of the structure and the material of the antifriction layer on the distribution of sites with different types of interaction in the contact area (adhesion, sliding and exfoliation), the value and character of the contact pressure and contact tangent stress. The analysis of the work of the three antifriction materials (fluoropolymer, antifriction composite material based on fluoropolymer with spherical bronze inclusions and molybdenum disulfide, modified fluoropolymer) for two variants of boundary conditions is made, the influence on the character of the contact interaction is established.
