Abstract: In this paper, a theoretical analysis of automatic vibration isolation for the impacting and vibrating systems with double masses is proposed, the concept of complete stability of discrete time systems is established and a criterion for complete stability is obtained. Finally, the above results are applied to the calculation of the inertia flask shakers an may be used as the theoretical foundation to solve the long open problem of strong vibration of the base of flask shaker.
