Influence of the convective cooling and the thermal resistance on the temperature of the pad/disc tribosystem

The analytical solution of a boundary–value problem of heat conductivity for a tribosystem, consisting of the plane–parallel strip (pad) sliding with a velocity linearly decreasing in time, on a surface of a semi-infinity foundation (disc) is obtained. It is assumed, that the thermal contact of bodies is imperfect and the convective heat exchange with the surrounding occurs on an upper surface of the strip. For materials of frictional pair, i.e. the ceramic–metal strip and the cast-iron foundation, the influence of the coefficients (of both heat exchange and heat transfer through a surface of contact) on the distribution of temperature has been investigated.
