Алгоритмічне та програмне забезпечення САПР структурних елементів великої кривизни

Abstract

The technological processes of textile industry come forward a research object, and the system of serve of filaments comes forward the article of research. A purpose consists in the got dependences of initial натягу of textile filament on the radius of curvature sending of surface of large curvature, entrance pull, corner of scope, type of raw material taking into account correlation of radius of crossing of filament and internal radius of sending taking into account inflexibility on a bend, deformation in the area of contact, nonlinear dependence to the coefficient of friction from entrance pull and radius of curvature of surface in a normal plane. Optimization of pull of textile filament before the working area of technological equipment (area of knitting, forming of fabric, sewing together of details of clothes) from position of his minimization allows to decrease the precipices of filaments, time of stop of technological equipment and to promote quality of products that is produced. Theoretical basis at the decision of scientific and technical problem are labours of leading scientists in industry of textile production, mechanics of filament, mathematical design. The methods of integral and differential calculation, theoretical mechanics, planning of experiment and statistical treatment of results of researches are utillized in theoretical researches. A task consists in diminishing of oscillation of pull of filament before a working area by the improvement of structural parameters of the system of serve of filament on the basis of optimization of structural parameters of component elements and real law of change of pull of filament.
