Prospects of application of vibratory devices in military equipment

Abstract

Possibilities of employing vibratory devices as conveying mechanisms in some models of military equipment, in particular in engineering weapons, are considered. Vibratory conveyors, which are widely used in industry for moving products over short distances, are mainly devices with one-component rectilinear oscillations, in which at the high conveying velocity the modes of movement with hopping are implemented, that is unacceptable for conveying many military facilities, including weapons and explosive objects. Vibratory conveying in non-hopping modes (without tossing) at high speed is possible when using independent (two-component) horizontal and vertical oscillations of the working body of the vibratory conveyor. Based on the analysis of the influence of oscillation parameters on the velocity and stability of vibratory movement of objects in non-hopping modes, a conclusion is made about the feasibility of using horizontal harmonic oscillations in near-resonant mode and vertical oscillations with piecewise constant acceleration. The equations describing the optimal law of vertical oscillations, which consists of two segments of parabolas during the period of oscillations, are derived. A constructive scheme of the vibratory conveyor based on a three-mass oscillating system with an unbalanced vibratory drive of horizontal oscillations and eccentric vibratory drive of vertical oscillations is proposed. The working body of the vibratory conveyor is connected to the intermediate frame by an elastic system of vertical oscillations, the stiffness of which is adjusted to a mode far from resonance. The reactive frame is connected to the intermediate frame by an elastic system of horizontal oscillations, the stiffness of which provides near-resonant mode. The presented vibratory conveyor significantly enhances the conveying velocity in non-hopping modes, which are required for conveying explosive objects, as well as increases the lifting angles and reduces the vibration transmitted to the environment, which will facilitate its use in military machines. It also outlines a number of issues that need to be addressed in the design and implementation of such devices in military equipment.
