| Abstract: | We study the problem of free and forced vibrations of a mechanical system modeling the functioning of seismic isolation systems
of “kinematic foundation” type in the case when the sliding friction damper is not centrally located. We determine the damping
characteristics in the case of free vibrations and the critical values of the damping parameter for the case of forced vibrations.
For the case of resonance vibrations with one degree of freedom we establish the relation of the increase in the amplitude
of the vibrations to time at subcritical values of the friction.
