Possible influence of external factors on the reduced stiffness of the system

Approach of change of dynamical condition of vibroprotection systems through introduction of additional con-nection force influence are considered. Such approach accordances to form of automatical control by force of influence. Key moment in formation of offering method is presence two (at least) external influences in relation which are supposed installation possibility of function tie. Usually form of tie are considered in the form con-stant coefficient between amplitude meaning of external influences. Sign of coefficient is taken into account. Change coerced rigidities possibilities are shown that is change her parameters at different coefficients of tie. Influence processes on state ties of systems related to change frequencies own oscillations possibilities, dynam-ical absorbtion regimes and other.
