摘要/Abstract

摘要：

针对立达第3代集聚系统的气流导向元件在生产中左右偏移的现象,分析了该现象对集聚效果的影响。选取气流导向元件的居中位置,以及左右各偏移1.5、2.5 mm共5个特征位置,使用Fluent软件对集聚系统流场进行数值模拟,并通过CFD软件对模拟结果进行数据分析。对比分析后发现,在发生1.5 mm和2.5 mm偏移时,集聚区均出现不同程度气流速度和静压大小的变化,包括集聚范围缩小、集聚气流速度忽高忽低和集聚处静压降低等。通过纺纱实验对模拟结果进行验证后得出:气流导向元件发生1.5 mm偏移时气流速度和静压大小改变引起的成纱质量波动较小,而当偏移量达到2.5 mm时成纱条干不匀上升3%,毛羽指数增加了8%,其影响趋势与理论研究结论相吻合。

Abstract:

The air guide element of the third generation Rieter compact system shifts in production line, in order to analyze the influence to the compacting effect, five feature points including the center point, 1.5 mm and 2.5 mm shifting to left and right were selected. Fluent software were adopted to simulate the flow field and using CFD software to analyze the results of the simulation. Results show that the shift of 1.5 mm and 2.5 mm causes variation in airflow velocity and hydrostatic pressure. Spinning experiment verifies the simulation analysis results. It is concluded that when the shifts is 1.5 mm, the yarn quality variation is small, but when the shifts is 2.5 mm the yarn quality varies obviously, and the yarn evenness increases by 3% and hairiness increases by 8%.

Key words: compacting system, air guide element, shifting, flow field simulation, compacting effect
