The Optimal Design of a Friction Unit with Uniform Contact Pressure

Abstract

In this work the displacement function of the external contour points of a hub and the friction surface microgeometry that correspond to the uniform distribution of the contact pressure over a friction surface are theoretically determined. The model of a rough friction surface is used. A closed system of algebraic equations is constructed that allows solution of the optimal design problem for a friction unit with account for the geometrical and mechanical properties of its elements.
