The results of numerical simulation of nonstationary thermal fields in cylindrical friction junctions are presented. On the basis of the marching method, a numerical algorithm which imposes no restrictions on the value of heat flow separation coefficient is constructed. Simulation results are given for different bearing designs both for the two and three-dimensional cases. Using the developed algorithm as a base, a method allowing for reconstruction of heat release and, hence, friction moment values from temperature measurements in the stationary unit element is suggested. Reliability of the results is proved by experiments.
