Mathematical model of mechanical system of vibrational volumetric treatment

In order to calculate designed parameters for vibrational machine of volumetric vibrational treatment with the purpose to increase its productivity, the technique for investigating its dynamics based on non-linear complex mathematical model of the "vibromachine - treating medium" - system is suggested in this paper. As an example models of the machine with two independently driven vibrational exciters and the treating medium of its container are described.
