Purpose - to develop research methods and calculation of the dynamics of strongly nonlinear vibrosistem with asymmetric elastic characteristic . Methods of research - the exact method of the fitting ( circular stitching) , the asymptotic method of expansion in the small parameter . The mathematical model of nonlinear oscillations with asymmetric vibrosistem elastic characteristic , which constitute nonlinear differential equations of motion with the motor characteristics . To solve these equations used a modified asymptotic method that allows us to refine the first approximation solutions with input from the higher harmonics. The resulting refined analytical dependence of the dynamic parameters of the presence of higher amplitude-frequency harmonics that occur not only on the non-linearity of the elastic ties, as well as the non-uniformity of the motor. Obtained in closed form suitable for further analysis and practical calculations , the solution of the problem of periodic oscillations of nonlinear systems with strongly fractured characteristics of the elastic forces with a method that is based on a combination of the fitting precision of the method ( circular stitching) and the asymptotic method of expansion in the small parameter . The decomposition of the resulting analytical solutions in the Fourier series gives detailed information about the spectrum of vibrations - the amplitudes and phases of all the harmonics of displacements and accelerations. Numerical calculations for the study vibratory in different variations of the nonlinear asymmetric rigidity and suspension stiffness ratios of non-linear to linear relationships . A solution of the problem of periodic fluctuations dvomasnoy nonlinear asymmetric vibratory and resiliently mounted on her workload (for example , forms with concrete ) in a closed form . The novelty of the work lies in the development of theory and methods for studying the dynamics of vibrosistem implementing asymmetric vibrations , new knowledge about the laws and the specific features of their behavior. Scope - the engineering, construction , mining and metallurgical promyshlennost.Prognoznye assumptions about the development of the object of study - the calculations of dynamic parameters and the development of working drawings asymmetric vibroconveyor , facilities for vibrozabivannya piles.
