摘　　要：针对传统针织圆纬机复杂的机械加工架构及高能耗编织模式,提出利用电磁-永磁悬浮直接驱动织针编织模式,简化传统圆纬机的机械传动结构。在已有工作的基础上,分析电磁力驱动的永磁织针受力模型,揭示多织针轴向悬浮运动的规律,建立悬浮织针轴向驱动模型及控制算法,实现传统圆机的三功位编织工艺并以零传动无损模式高速驱动织针;探索织针阵列悬浮驱动编织的特定方式,为悬浮驱动织针取代传统编织工艺,实现编织工艺的全程可控可调提供理论参考和试验方法指导。According to the complicated mechanical processing architecture and high energy consumption of the knitting pattern of conventional circular jacquard knitting machine,it presented weaving pattern using electromagnetic-permanent directly driving knitting needle,and simplifying conventional mechanical transmission structure of circular weft knitting machine. This paper analyzed permanent knitting needle force model driven by electromagnetic force on the basis of previous work,revealed the law of multineedle suspension motion in axial direction,established suspension knitting needle axially driving model and control algorithm,realized conventional circular machine knitting process in ＂ trip-work station＂ and drove needles in ＂ zero-transmission＂ in lossless model,explored multi-needle suspension driving woven in particular way,and provided theoretical guidance for further exploring suspension driving needle to replace conventional technology in weaving process and for the realization of control and adjustment in whole knitting process.
