Abstract
In the paper there is proposed computer model of the contact of friction materials in the brake devices of building road machines and lifting transport machines at different temperatures. The contact surface is modeled by a microrelief composed of a set of elements in the form of rods. As a result of modelling, there are such contact characteristics as rapprochement, distribution of contact pressure, real contact area and the gap between the surfaces. The obtained dependencies are compered with the finite element method. Keywords computer model of contact at diggerent temperatures, temperature influence, contact of friction material, actual contact area, contact pressure distribution
