Fluctuations in systems with a discrete number of degrees of freedom with dry friction
The approximate analytical for solving problems of forced oscillations f mechanical systems with discrete degrees of freedom, taking into account dry friction forces. Dry friction is replaced by an equivalent viscous resistance. For this purpose, the method of own functions for systems with discrete degrees of freedom is used to allow replacing the original system with some equivalent system. Thus there is postulated the equality of frequencies of original and present systems. The proposed method is illustrated by the example of the oscillating system with two degrees of freedom.
