Developed a dynamic mathematical model of the system and “drum-base” on grade, describing the vertical and horizontal rotational oscillations in structural elements debarking drums and their foundations. To develop a dynamic model of vibration foundations debarking drums accepted model of the subsoil NP Pavlyuk - E. Rausch with lumped parameters. Realized in the medium to MathCad models performed simulations and determine the natural frequencies and amplitude-frequency characteristics of all generalized coordinates in structural elements specific debarking drum and base. With Studies debarking drum KБ-425 are shown graphically oscillation parameters of system elements. The paper made ​​a synthesis of research leading to the use of models and programs in research vibration debarking drums and foundations all sizes by simulation.
