Abstract

Розробка програмних компонентів при комп’ютерному визначенні натягу нитки на снувальних машинах при підготовці основи з використанням алгоритму рекурсії дозволяє на початковому етапі визначати технологічні навантаження, які будуть виникати в процесі снування в залежності від виду сировини, якості підготовки бобін. Комп’ютерне визначення зміни відносного натягу на снувальних машинах при підготовці основи для виготовлення багатошарових технічних тканин спеціального призначення базується на чисельному розв’язанні трансцендентних рівнянь з використанням алгоритмів рекурсії та дихотомії.

The development of software components for computer determination of thread tension on winding machines, in the preparation of the base using the recursion algorithm, allows at the initial stage to determine the technological loads that will occur during warping depending on the type of raw material, quality of spool preparation. Computer determination of the change in relative tension on dream machines in the preparation of the basis for the manufacture of multilayer technical fabrics for special purposes is based on the numerical solution of transcendental equations using recursion and dichotomy algorithms. Calculation of changes in relative tension on winding machines in the preparation of the basis for the manufacture of multilayer technical fabrics for special purposes allows at the initial stage to determine the technological loads that will occur during warping depending on the type of raw material, quality of spool preparation. The change of tension occurs due to the interaction of the warp threads with the guides of the winding machines of large and small curvature, tensioning devices. The development of software components in the computer determination of thread tension on spinning machines should be based on the use of object-oriented programming languages. Determining the change in relative tension in the refueling zones of the sweeping machine, taking into account the design of the unit for tension, will improve the technology of warping in the preparation of the basis for the manufacture of multilayer technical fabrics for special purposes. Improvement of technological processes of warping should be based on complex researches of process of interaction of warp threads with devices for a tension, directing surfaces of big and small curvature. Theoretical dependences of the warp tension will allow to obtain mathematical software used in a computer program to calculate the change in relative tension in the refueling zones of the spinning machine, reduce the percentage of breakage of warp threads, improve the quality of weaving thread. Many studies do not take into account the change in the input tension of the warp thread when it is wound from the spool. This leads to significant differences between the theoretical and experimental dependences of determining the change in relative tension in the refueling zones of the dream machine, which does not allow to obtain reliable results.
