摘　　要：针对超宽门幅高速自动织机引纬困难的问题,提出基于电磁发射的超宽门幅自动织机引纬方法。根据超宽门幅自动织机对引纬机构的特殊要求,探讨了线圈型电磁发射引纬机构的设计方法。依据超宽门幅自动织机引纬工艺需要,建立夹纬器最大飞行速度分析计算模型,分析线圈型电磁发射引纬机构的组成和工作原理,研究线圈型电磁发射引纬机构的磁场特性,采用不同方法分析计算引纬电磁力,并进行了计算机仿真。结果表明:7级线圈发射做功182.21 N·m,可满足超宽门幅自动织机引纬174.64 N·m的要求。In order to solve the problem that the weft insertion is difficult in the development of the super width automatic loom,the weft insertion design method based on the coil electromagnetic launch for the super width automatic loom was proposed innovatively. According to weft insertion process requirements on the super width automatic loom,the analysis and calculation model of the maximum flight speed of the clip weft device was established. The composition and working principle of the coil electromagnetic launch weft insertion mechanism were analyzed. The magnetic field characteristics of the coil electromagnetic launch weft insertion mechanism were researched. The weft insertion electromagnetic force was calculated by different methods,and was simulated by computer. The results of analysis and calculation show that the 7 stages coil launch work is 182. 21 N·m,which can meet the requirement of 174. 64 N·m of the weft insertion of the super width automatic loom.
