摘　　要：基于课题组前期开展的悬浮式驱动织针理论及织针动态特性研究以及悬浮式驱动系统,为了大幅度提高编织效率,降低针织机能耗,深入研究悬浮式织针的运动机理,分析织针的最高工作频率及高效工作模式,以实现传统机械编织工艺的彻底取代。从运动模型和工作频率上分析悬浮式织针3功位工作,测量悬浮式织针的工作频率,给出各种电磁激励下织针运动的机械频率,测试最高激励频率下织针的机械运动,计算针织提花圆机的悬浮编织效率。结果表明,在电磁-永磁混合驱动模型下,悬浮织针3功位高速编织,编织效率可达18.500Hz,比传统机械编织工艺提高一倍以上,完全可以取代传统顶针机械编织工艺。In order to greatly improve the knitting efficiency and reduce the knitting machine's energy consumption,and based on the research of suspension-driven knitting needle theory and dynamic characteristics of knitting needle and suspension-driven knitting system carried out earlier by the research group,the motion mechanism of suspension knitting needle is deeply studied,and the highest working frequency and highly efficient working mode of the knitting needle are analyzed,so as to completely replace the traditional mechanical knitting process.This paper analyses the 3-position work of suspension knitting needle from the motion model and working frequency,measures the working frequency of suspension knitting needle,gives the mechanical frequency of the motion of the knitting needle under various electromagnetic excitations,tests the mechanical motion of the knitting needle under the highest driving frequency,and calculates the suspension knitting efficiency of the knitting jacquard circular machine.The results show that the efficiency of suspension knitting needle can reach 18.5 Hz in 3-position under electromagnetic-permanent magnet hybrid driving model,which is more than double that of traditional mechanical knitting technology,and can completely replace the traditional needle lifting knitting technology.
