Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | A nonlinear mathematical model of translational vibrations of a system of n
rigid bodies is constructed for the case of inertial loading. The system contains the supportball
mechanism of seismic isolation and the electromagnetic dampers, controlled by means of the inertial
feed-back channel. When the accelerative damping being presented in the system, the system of
differential equations of dynamics is obtained in the normal form. The frequencies of small
non-attenuated vibrations are evaluated. A technique of studying the dynamical coefficients by use
of acceleration of rigid bodies is proposed for the case of accelerative damping. For the
two-mass system, the phenomenon of double phase-frequency
resonance is studied. |
