Abstract
The article presents an assessment of the influence of parameters characterizing the macro-roughness on the surface of the brake disc on the distribution of contacting forces in the system "poly-clamping mechanism – brake pad – brake disc" and the developing brake disc. The angles of inclination of the real surface profile in the tangential and radial directions were chosen as the main parameters characterizing the macro-roughness on the working surfaces of the brake disc. Dependences were obtained for calculating the position of the center of pressure in the tangential and radial directions in the "poly-clamping mechanism – brake pad – brake disc" system, taking into account the angles of the profile inclination in two directions. To assess the effect of the inclination angles on the distribution of forces over the area of the contact surfaces of the brake, solid models of braking devices with simulated real profiles of the working surfaces of the disc were built. Disk surfaces with cyclic macroroughness and with one area were used as modeling objects. When the working pairs of the braking device interacted with one macro-roughness on the surface, an inversion of the distributed contacting forces occurred, in comparison with the disk on the surface of which there were cyclic macroroughnesses.
