Khomenko A.P., Eliseev S.V., Artyunin A.I. The issues of developing mathematical models of mechanical systems with dynamical absorbers through links coupling

The issues of developing mathematical models of mechanical systems with dynamical absorbers through links coupling

Khomenko A.P., Eliseev S.V., Artyunin A.I.

The paper deals with a general theory of lever dynamical vibration absorbers in mechanical systems intended to protect machinery and equipment from vibration and stresses. Desirable effects will be achieved by making proper couplings between the system links which results in reducing the number of freedom degrees of the system movement. Possibilities of using several systems of coordinates for describing the system dynamical properties depending on the element location and support are discussed. The paper considers the ways of eliminating some coordinates of relative movements provided they could be equal zero under specific conditions. Such approximations form link couplings and mechanisms in vibration system structure which can change the system dynamics. New means for controlling vibroprotection system dynamics could be developed. A number of examples are given based on mathematical modelling.

Keywords: vibroprotection systems, dynamical absorbers, lever mechanisms.

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

Eliseev S.V., Artyunin A.I., Bolshakov R.S.

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.

Keywords: lever ties in dynamical systems, structural interpretations of mechanical systems, generalized tasks of vibroprotection and vibroisolation.
