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.
