Vibrodiagnostics of dry friction in oscillatory system at kinematic excitation of forced vibrations

The method of vibrodiagnostics the dynamic system with dry friction at kinematic impact on it through the base part is considered. The method is based on definition a critical frequency of unblocking the fric-tional link and its dependence on magnitude of dry friction, possesses invariancy to viscous resistance and ensures the opportunity of in-place identifications of dry friction force in the object with inaccessible from the outside location of vibratory system or at its extrasmall dimensions.
