The process of heat conduction through periodically contacting rods has been considered. On the basis of the method of eigenfunction expansion of the boundary-value problem an evolutionary algorithm for constructing a solution for any cycle of contacting has been proposed, an explicit solution for the first cycle has been found, and a computer program of temperature field calculation with a given accuracy from the viewpoint of the proposed mathematical model has been developed. The dependence of the total heat resistance to the thermal flow through periodically contacting metallic surfaces of two rods in the presence or absence heat resistance on the material of the contact pair, the temperature conditions, the landed forces, the geometry of the contacting surfaces, and the contact frequency and time has been established experimentally.
