THE IMPROVEMENT OF THE TENSION OF THE WOOD SAWDUST INTO THE EXTRUSION AREA OF THE PELLET-MILL WITH THE CIRCULAR DIE [№ 1 ' 2015]
Pellet-mills are widely used in the production of pellets from raw materials of vegetable origin. Starting from the 20-ies of the last century they were used for pressing feed, and lately they are used for pressing of wood sawdust. Because of this there are the problem of the optimal design of such working elements of the pellet-mills. The solution lies in to conduct identification and verification of mathematical models of the extrusion process in semi-pressing into the working elements of the pellet-mill. For one of the same models which describes the stress of the extruded semi-finished product on the contact surfaces of working elements: the circular die and the pressing roller, such a procedure was performed. Based on the results of the experimental determination of the normal to the surface of the pressing pellet-mill roller extrusion tension softwood sawdust with the humidity of 10% and identification of a mathematical model of the tension state of the semimanufactured material in the areas of the lag and lead wedge workspace of the pellet-mill was refined theoretical description of the tension state in the area of semi-finished extruded — distribution extrusion area normal tension and shear tension on the contact surfaces of the die and the press roller between which there is a differential dependence.

TENSION OF THE PLASTIC BODY PRESSED IN SCREW THE CHANNEL OF EKSTRUDER [№ 9 ' 2013]
On the basis of model of an elastic and plastic body the tension of a pressed material in the channel of a screw press is considered, influence on developed tension of parameters of a pressed material and channel parameters screw is investigated. Limiting tension which can develop a screw press is defined.

THE MATHEMATICAL MODEL OF THE PROCESS OF THE EXTRUSION OF THE HIGHLY FILLED PLASTICS [№ 10 ' 2010]
The authors examined the mathematical model of the process of the extrusion of the highly filled plastics with the use of methods of mathematical simulation, determined five parameters of the effect of process — productivity of press-extruder, power of the forces of useful resistance, effort, which acts on the operating units, pulse of the comprehensive compressive voltages, efficiencies of the single-screw pressing mechanism, making it possible to adequately estimate process extrusions.

THE PROCEDURE OF QUANTITATIVE ASSESSMENT OF THE INFORMATION VALUE OF THE DOCUMENTS OF THE COMPLETE SET OF PROJECT DOCUMENTATION [№ 9 ' 2010]
The work examines the procedure of the synthesis of project documents, which ensures increase in their quality due to the use of the quasi-structure models of their information filling. The mathematical interpretation of the model of the quasi-structure information filling of electronic documents is examined and the parameters of the quantitative assessment of the information value of a document according to its model are proposed.

FORMING OF OBJECTS WITH USING OF VECTOR OPTIMIZATION METHOD [№ 12 ' 2004]
This article is devoted to modern technologies of knowledge search in data. Classification of general methods and algorithms of data intellectual analysis at general components is given here. Method of intellectual analysis adapted to data archives keeping information about technical objects work, is described in this article. This technology is based on the methods of vector optimization. A person, took a decision (PTD) manages the analysis process.

MOVEMENTS OF A MATERIAL IN SCREWS` CHANNEL AT PRESENCE OF THE BOUNDARY LAYER AT THE BOTTOM OF THE CHANNEL [№ 9 ' 2004]
On the flat model the movement of a material in the screws` channel is analysed at presence of a boundary layer at the bottom of the channel on which creeping of a material occurs. The condition is received determining the character of movement of a material depending on relative speed of movement of working bodies and a gradient of pressure in the channel. The parameter is offered - the effective pressure, allowing to characterize the processing influence on extruded article.
