Comparative Experimental Study of Friction Parameters in a Tribopair and a Force System

Abstract

The paper presents the results of experimental study of the effect of stresses resulting from off-contact load on variations in the friction torque and the coefficient of resistance to rolling in a force system compared to a similar tribopair. The results are compared with the theoretical data obtained on the basis of the deformation approach to the analysis of friction. It is shown that the calculation estimates agree well with the experimental results both qualitatively (the regularities) and quantitatively (the numerical values). The error of the determination of the coefficient of resistance to rolling does not exceed 7%. The study results make it possible to formulate and solve the problem of the effective control over the friction force (coefficient) by varying cyclic (bending) stresses.
