В данной статье рассмотрены вопросы повышения
динамического баланса гребня (reed system) в ткацком станке, увеличения
устойчивости процесса прокладывания утка и минимизации вибраций.
Исследование проводилось на станке CHEONG WOON 200 производства
Южной Кореи. Изучено влияние вибрационной динамики гребня и
инерционных сил на точность размещения нити. Для описания движения
системы использовались уравнения Лагранжа второго рода и численные
методы моделирования. Надёжность модели была подтверждена
компьютерной симуляцией вибрационного процесса с применением
программных комплексов MATLAB и ANSYS. Результаты показали, что
оптимизация параметров жёсткости и демпфирования позволяет
снизить амплитуду вибрации на 18–22 % и повысить энергетическую
эффективность механизма на 12 %. Кроме того, время затухания
вибрации было сокращено до 0,2 секунды. Это подтверждает определение
оптимальных рабочих параметров, способствующих продлению срока
службы оборудования. Полученные результаты могут быть использованы
при проектировании и модернизации ткацких станков, а также для
повышения эффективности их работы.
This paper focuses on the dynamic balancing of the reed system for weaving
looms to enhance the stability of the beating-up process and minimize vibrations.
Special attention is given to analyzing the reed system’s oscillatory dynamics and the
effect of inertial forces on weft placement accuracy. The research employs numerical
modeling methods, including the second-order Lagrange equations, to describe the
system’s motion. We utilized MATLAB and ANSYS software tools to verify the accuracy
of the developed model and simulate the oscillatory behavior. The study results indicate
that optimizing stiffness and so’nish parameters can reduce vibration amplitude by
18–22% and improve the energy efficiency of the mechanism. We also identified optimal
operating parameters to prolong the equipment's service life. The findings can be
applied in the design and modernization of weaving looms to enhance their operational
performance.
