Vibrating bunker feeders are commonly used to automate production processes. They are widely manufactured by different world enterprises: Spirol International Corporation, Moorfeed Corporation A Division of Executive Automation Systems Inc., NTN Corporation. [1-5]. Two main types of vibration bunker feeders can be distinguished: with directed (fig. 1) and independent (fig. 2) oscillations. In vibration bunker feeders with independent (elliptical) oscillations, the direction of throwing is provided by force disturbance at two independent coordinates. Therefore, for determining the coefficients of stiffness of elastic nodes, we use well-known expressions for the consolidated mass at rectilinear oscillations or the consolidated moment of inertia of the system at angular oscillations [6-10]. a) b) Fig. 1. Vibrating bunker feeders with guided (screw-like) oscillations in which the bowl is made cylinder-like (a) and a conical-like (b) In vibration bunker feeders with propeller oscillations, the direction of throwing is ensured due to sloping elastic elements. In such structures, the propeller movement involves two: rectilinear and angular. Therefore, in order to determine the stiffness coefficient of an elastic node on the basis of a hyperboloid torsion, it is necessary to know the consolidated mass or the summed moment of inertia at propeller-shaped oscillations, which themselves contain, respectively, the proportion of the consolidated moment of inertia of the system at angular oscillations or the consolidated mass in rectilinear oscillations [11,12,16]. Fig. 2. Vibrating bunker feeder with independent (elliptical) oscillations In the technical literature you can find methods for calculating vibration bunker feeders parameters. One of the defining parameters is the consolidated mass or the summed moment of inertia of the oscillatory system, the motion of which is carried out on a propellant trajectory. It is impossible to c[...]
