IMPROVEMENT OF WORKING BODIES’ FORMS FOR DEVICES FOR FORAGES PREPARATION BY METHODS OF ENGINEERING GEOMETRY AND COMPUTER GRAPHICS

abstract 1291705047 issue 129 pp. 578 – 598 31.05.2017 ru 102
Improvement is offered for working bodies’ forms in devices for preparation of forages by methods of engineering geometry and computer graphics. That opens not only great opportunities for intensification, increase in productivity and efficiency of the technological processes, but also opens ways for creation of small-sized devices for their realization. Constructive study of geometry of working bodies surface, allows us to give wavy movement to particles of forage and impart them the movement with bigger power consumption. In such installations forage particles components, meeting walls of working body, change their direction and, meeting other portions of particles of forage components, mix up. From loading to unloading, throughout the installations working body length, flexible and strong waves of forage particles components movement inside the working body are born. The conducted pilot studies have shown that as a result of working bodies’ forms improvement of devices for preparation of forages by methods of descriptive geometry such devices can be implemented in a variety of industries

MODELING OF CONTACT FORCES IN THE CONCENTRATED FORAGES COMPONENTS’ MOVEMENT IN RELATIVE SCREW DRUMS

abstract 1251701026 issue 125 pp. 377 – 396 31.01.2017 ru 122
Analytical research results of contact forces of interaction of concentrated forages components’ particles in their movement in relative screw drums are presented. It is shown that contact forces – the most difficult forces by their nature; result from stochastic (probable) collision of bulks particles and in particular of concentrated forages components’ particles. Therefore the main objective of this modeling – to describe the stochastic phenomena of the so-called conditional contacts of particles for which some assumptions are accepted, for example, in forcing of mass of concentrated forages components’ particles by the walls of the rotating relative screw drum in the radial direction there will simultaneously arise contacts caused by geometry of a screw drum, i.e. the property of its walls is pressure transfer in relation to the mass of particles in the direction of the modeled movement. Schemes of engagement of concentrated forages components’ particles contacting in the relative screw drum, the probable schedule of sliding speeds values change in their consecutive contacting, their density distribution are demonstrated
