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.
