For three experimental dependences used to describe the changes in the specific power of friction as a function of the braking time, we construct the exact solutions of the corresponding thermal problems of friction. For this purpose, we use the Duhamel formula and the well-known analytic solution of a one-dimensional boundary-value problem of heat conduction for two semiinfinite bodies and a constant power of friction on the contact surface. We illustrate the application of obtained solutions to modeling the process of friction heating of a pad–disk tribosystem. We also study the influence of the chosen time profiles of friction power on the temperature distribution in a cast-iron (ChNMKh) disk and in a pad made of FM–16L retinax.
