摘　　要：为更好地控制双针床经编机成圈过程中纱线张力的波动,以RDJ4/2 EL型双针床经编机为研究对象,测试不同运转角度下的纱线需求量和纱线张力的波动曲线。通过分析导纱针-织针处的瞬时需纱量和梳栉-导纱针的瞬时需纱量发现,相比导纱针-织针处的瞬时需纱量,梳栉-织针瞬时需纱量的波动程度增加了231.5%;分析整体瞬时需纱量和纱线张力的波动趋势发现,纱线张力和梳栉-织针瞬时需纱量具有相似的增区间和减区间,极值存在的角度区间也很接近。研究结果表明:梳栉整体的摆动增加了需纱量的波动范围,是影响瞬时需纱量和纱线张力波动规律的最主要因素,严重降低了纱线的稳定性。In order to study the influence of bar swing on instantaneous yarn demand and yarn tension fluctuation, based on the RDJ4/2 EL warp-knitting machine, the actual instantaneous yarn demand and yarn tension fluctuation at different running angle were measured. It is found from the calculation and analysis of the instantaneous yarn demand in the circle area and the instantaneous yarn demand of the guide bar that the fluctuation of the guide bar causes the fluctuation of instantaneous yarn demand by 231.5% compared with the form of motion with no bar swing. By comparing the fluctuating trend of overall instantaneous yarn demand and yarn tension, it is found that yarn tension and total instantaneous yarn demand have the similar increasing interval and decreasing interval, and have the similar interval of extreme value. Research shows that the swing of the guide bar increases range of fluctuations in the amount of yarn demand, and is the most important factor affecting the yarn tension and severely reduced the stability of the yarn.
