Harmonic linearization of equations of forced oscillations of systems with dry-friction elements

A general method of the harmonic linearization of equations of forced oscillations of mechanical systems with dry-friction elements for arbitrary relationships between the intensity of the exciting forces and the limiting force of dry friction is explained. It is shown that the equation normally employed for harmonic linearization is valid only in the case when the limiting force of dry friction in the element is significantly lower than the reactive force that can be developed in the element in the absence of slip. A computational example for a system using a more precisely defined method of harmonic linearization is cited.
