The subject matter of the study in the article is a mathematical model of the vibration system "machine-environment" taking into account the properties of the sealing medium. The goal of the article is to justify the design scheme and to create a mathematical model of the vibration system "machine-environment", taking into account the properties of the sealing medium for estimating the effect of medium resistance under poly-frequency oscillations. The tasks: to carry out theoretical studies of modeling and taking into account the effect of medium resistance under polyfrequency oscillations for compacting concrete mixes. The methods used are analytical studies of discrete and continual dynamic systems. The following results are obtained. The expressions obtained for determining the components of the medium's resistance under polyfrequency oscillations. Thus, applying these expressions, one can evaluate the influence of each of the harmonics of the vibrational process on the motion of the system and, respectively, the stress-strain state. This is a fundamentally new result and the idea of the possibility of creating a new generation of vibration systems on this basis. Conclusions. The justified calculation scheme and the mathematical model of the vibration system "machine-environment" is developed taking into account the properties of the sealing medium; an analytical method for determining the influence of the medium being processed on the dynamics of the "machine-environment" system; Analytic dependences for the estimation of the influence of the medium's resistance under polyfrequency oscillations are obtained.Downloads
