Abstract

Vibrational transportation-technologic (VTT) process is a dynamically sensitive process, in which many physically different components are involved: vibrodrive, elastic system, working member (absolutely or finitely rigid), various grainy loads. The interactions of those components define the behavior of grainy material on the surface of working member. As a main defining factor of the accuracy of the process, precise transmission of vibration to the working member is of particular importance. In the manuscript, the special dynamical model of the VTT system and corresponding mathematical model of the VTT process are presented, where the movement of grainy material is described under the conditions of spatial vibration of the working member, which is caused by possible errors in the manufacture and assembly of the vibration machine. Mathematical modeling has been carried out under continuous operating conditions (amplitude, frequency) of electromagnetic resonance vibrofeeder, when simultaneously alternating amplification of separate non-working spatial vibration and revelation of its impact on the process takes place. The results of modeling in the form of graphs and the influence of non-working vibrations on the law of the material displacement are presented in the manuscript.
