A mathematical model to analyse the influence of change of the friction power over time on
temperature of a pad-disc tribosystem has been proposed. For this purpose, a boundary-
-value problem of heat conduction for two semi-infinite bodies with taking into account heat
generation due to friction on the contact surface has been formulated. Exact solutions of
this problem were obtained for seven temporal profiles of the specific heat generation power,
which were established experimentally. For selected friction materials, numerical analysis of
the spatiotemporal temperature distributions and heat fluxes intensities were executed. The
obtained results were compared with a corresponding data which were found by means of
the known approximate solution.
