Oscillatory Processes and Vibration,t in all fields of technology, in everyday occurrence and nature. There is no in fact a domain where one or another kind of oscillations arises. The vibrations not envisaged at designing engineering objects are considered as undesirable and unsafe. It is important to understand the causes exciting t

Friction-Excited Self-oscillations,Friction-excited self-oscillations should be accounted for as an eventual source of vibrations in machines and mechanisms. This is one of the most spread types of mechanical self-oscillations connected with instability of the friction process under relatively low sliding velocities.
