Purpose: On the basis of the obtained rheological model of deformative powder mix that makes it possible to model its elastic and dissipative properties and also the friction between the particles; it s required to determine the character of the vibration exciter with powder mix at its vibrations in vertical direction; to determine the law of its motion, design parameters and modes of the vibration effect. Design/methodology/approach: The theoretical research of hybrid dynamic system “vibration exciter – powder mix” has been conducted; the system is considered as a system with the distributed. Physical and mechanical model, allowing sufficiently exact to define inertia, resilient and dissipative forces, operating from the side of powder-like mixture on a vibrating puncheon at his vertical vibrations, is developed. Findings: The expressions for definition of inertial elastic and dissipative forces that effect from the side of powder mix on the vibration exciter taking into consideration resistant force. Originality/value:The obtained theoretical dependences can be used in the design of technological equipment at measuring its basic parameters and the selection of rational modes of vibration effect on powder mixReferences
