摘　　要：为了实现对分离筘座式挠性剑杆织机电子引纬时纬纱张力和张力波动范围的有效控制,提高织物的品质,在对TT96型剑杆织机引纬机构改造的基础上,对不同纱线和不同引纬运动规律时纱线张力实验数据进行分析比较。结果表明:通过选用合适的纬纱储纬器、张力器和纬纱供纬位置,选用加速度峰值较小的改进型梯形加速度引纬运动规律,优化纬纱运动路径,可有效地降低纬纱的张力值和张力变化的幅度,达到对纬纱张力进行积极控制的目的,满足织造工艺的要求。In order to control the weft tension and its amplitude and improve the quality of fabric, the experimental data of yarn tension at different weft inserting motions with different yarns based on TT96 type rapier loom with electronic weft insertion partly modified were analyzed and compared. The results demonstrated that the weft tension and its amplitude can be effectively reduced and positively controlled to meet the requirements of weaving provided that suitable weft storage feed unit, Weft feeding position and tension device are selected, modified trapezoid acceleration motion with smaller peak acceleration as the law weft insertion motion is adopted, and the route of weft yarn motion is optimized.
