Self-synchronization of drive vibrators of an antiresonance vibratory conveyor

Abstract

A theoretical analysis of synchronization of inertial vibrators of a vibratory conveyor with a dynamic damper is presented in this paper. It is shown that for the over-resonance regime and counter-running drive vibrators, there is only one stable state of the system warranting formation of necessary sectional vibrations of the trough. The analytical form of the moment--synchronizing vibrators is also determined, and on the basis of this, the influence of angular vibrations of the body on the synchronizing process of the drive vibrators is determined. Due to the differences in the participation of angular vibrations in the self-synchronizing process in relation to classical solutions, the presented results fundamentally influence the design of long antiresonance conveyors.

Generating rectilinear, elliptical, and circular oscillations of a single-mass vibratory system equipped with an enhanced twin crank-type exciter

“…One of the major tasks set for a designer of the vibratory equipment consists in providing the prescribed trajectory (path) of the working member (conveying tray, screen, sieve, etc.). The possibilities of controlling the dynamic parameters of different vibratory systems equipped with centrifugal vibration exciters (unbalanced rotors) are comprehensively studied in [7] and [8]. The enhanced designs of inertial exciters based on the planetary-type mechanisms are presented and simulated in [9] and [10].…”
