“…This behavior of the material is related to the joint contribution of its viscoelastic and adhesive proper ties. It has been shown that, with molecular forces act ing in the contact zone, the normal loads affect the coefficient of sliding friction, which decreases with increasing load [11]. The filling of rubber with ultrafine PTFE leads to a decrease in the molecular interaction forces that act between rubber and the steel surface, as well as to a substantial weakening of the effect of the normal pressure on the coefficient of slid ing friction.…”

The results of an experimental study of the effect of the normal pressure in the range of 0.1-0.3 MPa, a velocity of sliding of 1-100 mm/s, and a bulk temperature of 22 to -27°C on the coefficient of sliding friction of an elastomer-steel friction pair have been presented. Two types of elastomeric materials have been considered, i.e., frost resistant rubber based on synthetic propylene oxide rubber and this rubber filled with the antifriction additive of ultrafine polytetrafluoroethylene powder in an amount of 1 weight part per 100 weight parts. The results have shown the efficiency of filling rubbers with ultrafine polytetrafluoroet hylene; the coefficient of sliding friction at temperatures below -15°C decreases by more than two times.

“…The regime of interaction in the gap should be appropriately chosen for each strip depending on the value of D j i -saturated contact, partial contact with saturated adhesion, partial contact with discrete regions of adhesion, or absence of contact. Detailed description of the method of solution of the 2D contact problem with different regimes of interaction is given in [17], and description of the strip method for the problem in question is given in [18,19].…”

“…An alternative approach to including adhesion forces into modeling the hysteretic friction is considering attraction force acting in the gap between the surfaces in the direction normal to the surface. The method of solution for such contact problems for a viscoelastic foundation in sliding contact with a wavy surface indenter was suggested in [17] for the 2D case and in [18,19] for the 3D case. The formulation of these problems implies only normal forces acting in the contact, the tangential force (friction force) being calculated as a result of hysteretic response.…”

A model for calculating the hysteretic friction force for a multilevel wavy surface sliding in dry conditions over the surface of a viscoelastic foundation is suggested, taking into account adhesion force acting in the direction normal to the contact surface. At each scale level, the contact problem for a 3D periodic wavy indenter is solved by using the strip method to reduce the problem to 2D formulation in a strip. Different regimes of contact and adhesion interaction are possible in each strip, including partial and saturated contact. The friction force is calculated as a sum of two terms. The first term is due to hysteretic losses occurring when asperities of this scale level cyclically deform the viscoelastic foundation during sliding. The second term is the law of friction determined from the solution of the contact problem at the inferior scale level. For the case of a two-level wavy surface, the contribution of both levels into the total friction force is calculated and analyzed depending on the sliding velocity and specific energy of adhesion of the contacting surfaces.

“…A method of analytic solution of contact problems with adhesion in 3D formulation was suggested for a viscoelastic foundation in sliding contact with a separate spherical indenter 12 and wavy surface indenter. 13 The problems were considered under given penetrations of the indenters. Solution of the latter contact problem was obtained for the complete surface geometry—both tips of asperities and valleys between them.…”

Solutions of two three-dimensional contact problems for a linearly viscoelastic foundation in sliding contact with a separate indenter and a periodic wavy surface taking into account adhesion are presented. Based on these solutions, the influence of the complete surface geometry, that is, shape of both tips of asperities and valleys between them, on the contact characteristics and deformation friction force is analyzed for various values of the normal load, sliding velocity, and adhesion parameter.
