In the article the methods of identification of dynamic parameters forces dry uncoloumb friction are presented, which are responsible for the occurrence of frictional self-oscillations. As a model of the forces of dry uncoloumb friction adopted characteristic with «falling» of the land forces of friction of sliding speed. Identification of the parameters of this model is implemented by measuring, registration and subsequent computer processing of experimental data obtained in the course of carrying out of tests of studied materials of friction pairs. The method has been tested on the test stand for the identification and study of dynamic parameters of the forces of dry uncoloumb friction and allows to predict the possibility of friction of auto-oscillations in contact interactions, as well as to implement vibrodiagnostics different pairs of friction.
