Abstract
A theoretical analysis to determine a microgeometry of friction surface for the drum—lining pair is carried out. The sought-for microgeometry provides a uniform temperature distribution on the contact surface. The model of a rough friction surface is used. A closed system of algebraic equations is constructed. This system allows the solution of the optimal design problem for the drum- lining friction pair of the truck brake mechanism depending on geometric and mechanical characteristics of the pair elements. Keywords friction pair, drum, lining, wear, optimal microgeometry, uniform temperature distribution
