Regularities of interactions between elements of a spherical contact unit with an antifriction polymeric interlayer

A finite-element study of the interaction between the elements of a spherical contact unit with an antifriction polymeric interlayer in full three-dimensional statement is reviewed. The mathematical problem of the contact interaction of elastic bodies through the antifriction interlayer is formulated taking into consideration all contact statuses, i.e., sticking, slipping, and the separation of contact surfaces. A finite-element model of a design bearing with the spherical segment and the influence of operational loads upon its contact interaction is considered. The regularities of contact parameters distribution at action of operational loadings are revealed and integrated power reactions of the contact unit arising in the top plate at the joint action of vertical pressure and shift loading on spherical bearing are established.
