A purpose of work is development of scientific and applied bases creations high-efficiency енерго ощадних resonance oscillation machines with an electromagnetic actuator which will allow to create the large overall technological equipment of the various setting not depending on industry of the use. Research method. Work is based on the basic laws of theory of resiliency, keeping indoors outside the theory of linearness, and substantive provisions of theory of small mechanical vibrations. For mathematical description of small vibrations of dynamic model MKS after three degrees of liberty the system of the generalized equalizations of motion is utillized - three differential equalizations of Lagrange Ii-go to family. Disipativni of function is accepted as functions of Releya, where the coefficient of viscidity is proportional the rate of movement. The decision of differential equalizations was carried out by the method of mechanical impedance (after peak values). Determination of reactions and bendings in resilient elements was conducted with the use of the system of equalizations of moving in a canonical form. Computer design MOS carried out with the use of MATHCAD (construction of ACHKH, FCHKH, sentinel diagrams of motion of the masses on transient and withstand behaviors) and method of complete elements software for the leadthrough of static (determination of tensions, bendings is in the elements of the resilient system). The results are inculcated in the educational process of AKM department and on private enterprise "Politep" (Lviv). Keywords: an oscillation machine is with an electromagnetic actuator; between-resonance; three-masses mechanical oscillating system. Product Description popup.authors popup.nrat_date 2020-04-02 Close
