Abstract
This paper presents the system of equations of heat dynamics of friction and wear (HDFW) for the pad–disc tribosystems, accounting for the thermal sensitivity of materials and the dependence of the friction coefficient on the maximum temperature of the friction surface. The contact of two sliding layers with heat generation due to friction is chosen for simulation in the formulation of the corresponding thermal problem of friction. The solution to the HDFW system of equations is obtained using the method of lines. The calculations are performed for a cermet pad and a cast-iron disc. The variation in such interdependent characteristics as temperature, velocity, and friction coefficient is investigated in the braking process.中文翻译:
