On the approach to the complex research into the vibratory technological process and some factors having an influence on the process regularity

Abstract

Vibratory transportation and technologic machines are widely used for transportation and processing of the friable materials in many spheres of industry (agriculture, mining industry, construction etc.). At the same time, many factors influencing the process are not thoroughly revealed; among them, influence of so called parasitic vibrations of the working member is not studied sufficiently. A three- mass vibratory system, an analogue of the vibratory transportation and technologic system “vibro-drive – working member – technologic load” was studied holistically. A relevant mathematical model of the spatial interconnected vibra-tory movement is drawn up in the form of the differential equations. The real possible reasons of generation of the spatial vibra-tions in the mentioned systems and possibility of their influence on the technologic process are considered. The influence of the constructional errors and resulting spatial (non-working) vibrations of the working member on the regularity of the friable mate-rial vibratory movement is studied by mathematical modeling. The researches have shown that some non-working (so called pa-rasitic) vibrations in combination with the basic vibrations can improve the technological process - increase intensity of movement of the friable material. The graphical illustrations are presented.
