摘要：
A comparative evaluation of the applicability of elastoplastic and rigid-plastic force characteristics of dry friction to calculating contact-oscillating systems is discussed. It is shown that elastoplastic characteristics of the hysteretic type are applicable at amplitudes of oscillations less than or comparable with the ultimate predisplacement. The features are considered of the dynamic links in the sliding friction contact that may lead to the known least dependence of the force of friction. It is noted that application of rigid-plastic friction characteristics to calculation of low-amplitude quasi-elastic contact oscillations leads to contradiction with the experimental data.
