Some questions of dynamics of interactions in mechanical systems with lever ties

New approaches in formation of mathematical models of mechanical oscillation systems are considered. Is shown that general mathematical model in form of structural scheme of the equivalent in dynamical ratio of automatically control system. Models transformation permits to open for analysis dynamical interactions features between partial systems and type elemental part. Transformation structural schemes algorithms are offered which allow to secure calculation of lever ties which has rotation center in plane motion. And is shown that protection object is separated in oscillation system, remaining part of system can be curtailed in some structural “compact” which has features of generalized spring or dynamical elasticity.
