Objective
Engineering methods of computation of characteristics of metal-polymer friction pairs will be elaborated. They concern the actual area of contact, the level of deformation, contact shift, the contact rigidity, the structure of contact area, the friction coefficient, and the wear intensity. The problem of computation of closed activity on the friction surface will be worked out for the first time the quantity of closed cavities per unit of nominal contact area characterises the ability of a surface to hold grease.
The correctness of these computational methods will be proved by comparing computed values with experimental data and computation results obtained by other scientific methods. The contact interaction of the layer with initial stresses and elastic axisymmetric punches will be considered. Investigation will be carried out into the general form for compressible and incompressible materials with an arbitrary structure of elastic potential, separately for unequal and equal roots of the constructive equation.
The main solutions of the three-dimensional linearised elasticity theory of bodies with initial stresses will be used. Interaction with elastic axisymmetric punches is assumed to be the result of both axisymmetric and non-axisymmetric power. By applying the Hankel transformation this contact problem is reduced to paired integral equations.
