Wear Minimization of the Friction Pad Weakened by a Crack
Source abstract
Abstract
In this paper, we present a theoretical solution to the problem of finding the microgeometry of the friction surface, which ensures uniform wear of the friction pad of the brake mechanism and the immobility of the crack in the material. As is known, the friction pair of the brake mechanism wears unevenly, so it is advisable to reduce wear where its value is maximum. It is possible to achieve this goal by applying design and technological methods at the stages of designing and manufacturing a friction pair if the optimal microgeometry of the friction surface of the pair is known. The desired optimal microgeometry of the friction surface of the friction pair must also prevent the growth of possible cracks in the material. The stated optimization problem is solved using a model of a rough friction surface. Using the perturbation methods, the theory of analytic functions, and least squares, the problem is reduced to a problem for a conditional extremum of a function of many variables. A closed system of algebraic equations, which makes it possible to obtain a solution to the optimization problem for the friction “pad-brake drum” pair depending on the characteristics of its elements, was constructed. The resulting microgeometry of the friction surface provides an increase in the wear resistance and bearing capacity of the friction pad of the vehicle brake mechanism.
