摘　　要：为了改善织针的驱动性能,通过对密绕线圈阵列结构分析,确定悬浮织针的驱动结构,以提高空间磁场强度和悬浮织针驱动力;并根据毕奥-萨伐尔定律,推导密绕线圈阵列结构的电磁模型,分析计算不同密绕线圈结构及阵列方式在中心轴线上任意位置的磁感应强度,以及不同气隙高度下永磁织针的电磁驱动力;利用电磁仿真软件建立密绕线圈阵列结构驱动模型,得到单一式和阵列式密绕线圈结构对永磁织针所受电磁驱动力的数值曲线。最后通过搭建密绕线圈阵列驱动实验测试平台,对比仿真和实验结果。研究表明:圆柱形密绕线圈在永磁织针驱动系统中驱动性能更佳,且单组密绕线圈产生的驱动力大于多组阵列产生的驱动力。In order to improve the driving performance of knitting needles,through the analysis of the densely wound coil array structure,the driving structure of the floating needle was determined,and the spatial magnetic field strength and the driving force of the floating needle were improved.According to Biot-Savart law,the electromagnetic model of the densely wound coil array structure was deduced,and the magnetic induction intensity of different densely wound coil structures and array methods at any position on the central axis was analyzed and calculated,which gain the electromagnetic field of the permanent magnet knitting needles under different air gaps and driving force.An electromagnetic simulation software was used to establish the driving model of the densely wound coil array structure,and the numerical curve of the electromagnetic driving force of the single and array type densely wound coil structure on the permanent magnetic needle were obtained.Using the constructed densely wound coil array driving experiment test platform,comparative analysis of simulation and experimental results were achieved,showing that the cylindrical densely wound coil has better driving performance in the permanent magnetic needle drive system,and the driving force generated by a single group of densely wound coils is greater than that of multiple groups.
