摘要: 本文选用无停留修正梯形加速度曲线作为高速经编机电子横移的控制模型,在KS4高速经编机上进行不同条件下带梳栉实验,对比分析高速运动中梳栉驱动系统的适时动态响应特性曲线表明,选择该运动曲线作为高速经编机电子横移控制模型是合适的,并且具备良好的控制效果。实验同时表明,为有效提高车速,在针前横移区间,电子横移控制所采用的横移起始角度要超前于实际机械横移起始角,最大可到5°;而在针背横移区间,电子横移控制所采用的横移起始角度要滞后于实际机械横移起始角度,至少为20°;并且在两种情况下,电子横移控制所采用的横移结束角均要提前于实际机械横移结束角。

Abstract: This paper selects no-flat modified trapezoid acceleration curve as the electronic shogging motion control model used in high-speed warp knitting machine, and carries out with a load experiment in KS4 high-speed warp knitting machine. Under different experiment conditions, the real-time dynamic response characteristic of the high-speed shogging guide bar approved the selected acceleration curve is more suitable for the electronic shogging motion control and has a good control effect. Moreover, it is observed that, in order to improve the speed of warp knitting machine effectually, the start angle of electrical shogging should be earlier, the biggest can reach 5°, than mechanical shogging during the overlap; but should be at least 20° later than mechanical shogging during the underlap; and the two stop- shagging angle of overlap and underlap both should be earlier than mechanical stop-shagging angle.
