Abstract: | We give the mathematical statement and construct the solution of the static thermoelastic problem of contact interaction of
an elastic retaining ring with a circular hollow cylinder inserted in it. The bodies are compressed by a load varying along
the axis of the system under the conditions of load-free contact on the surface of the ring or along an arc of the circle.
In the case where radial displacements of the contact surface of the retaining ring are approximated by displacements of the
surface of a long circular hollow cylinder and the process of stationary frictional heat generation is taken into account,
we reduce the posed problem to systems of integral equations whose structure is determined by the type of conditions of thermal
contact. We propose a numerical algorithm for the solution of these systems and study the influence of the input parameters
of the problem on the distributions of contact pressure and temperature. On the basis of these results, we make a conclusion
that the influence of the character of variation of the compressive load along the axis on the distribution of contact pressure
is significant in the case where the kinematic conditions of interaction of the bodies are described by the Hertz theory.
