System Vibroprotection and Shock Protection with Dry Friction

Despite the large number of discussions about the systems of shock- and vibroprotection, little attention has been paid to vibro­protection with dry friction. The single-axis system of vibro- and shock protection with dry friction, which at the given level limits the maximum acceleration of the isolated body at the single high-level shocks and at vibrations with the absent static zone of stagnation near the equilibrium, is first considered in the paper. The system is designed for providing the operational protection of the navigation device, installed on the aircraft, against shock overloads of large am­plitude. The system design, principle of operation, the method for ob­taining the mathematical model are given in the paper, components of this model are shown. The obtained results prove the prospective of the new system of shock- and vibroprotection in use in navigation complexes of aircrafts, operating in extreme conditions
