Kuzmenko A.G. Contact mechanics of change of the compressed surfaces. Method and examples of calculations.

Abstract

In accordance with the theoretical decision of task about the change of the compressed surfaces a variation experimental method is develop a method and analysis of its practical use. On the basis of analysis of exponential function of distributing of tensions of friction on the compressed surfaces the mechanism of sliding friction is offered at a change.The methodical example of experiment on determination of functions of distributing of tensions of friction is executed at the change of surface of foam rubber. On the basis of analysis of decisions the model of influence on the wear of amplitude of the reversible sliding is offered at fretting wear. Enhanceable fretting wear at small amplitudes is explained the concentration of tensions of friction in initial part of contact.
