This article presents a spatial model of a vibrating conveyor supported on steel-elastomer vibration isolators and vibrated by two inertial vibrators as well as the results of analyses of the effect of the layout of vibrators on the operation of the conveyor. The displacement of the line of action of the resultant of the forces of the vibrators beyond the centre of mass of the machine body manifests itself in the departure of the machine body from the desirable rectilinear motion and problems associated with the unevenness of material movement. The model presented in this article takes into account an extremely important coupling between vibrators and the body of the machine, which is responsible for the process of self-synchronisation of the vibrators and the correctness of machine operation.
The results of theoretical analyses presented in this paper were verified by laboratory tests and reference to observations based on the authors’ industrial experience.
