摘　　要：目前第2代六角形编织机的编织工艺尚无明确的编写规则或方法,为解决上述问题,提出了面向管状织物结构设计的六角形编织工艺方法。首先,通过分析携纱器在角轮上的位置变换原理,提出了等效角轮理论。然后,结合六角形编织机结构及其运动特点,提出了编织机的等效角轮单元,介绍了在六角轮的底盘上构建六角形编织机等效角轮系统时,编织机所包含的底盘单元结构。其次,结合管状织物的结构参数和等效角轮的结构特点,建立携纱器排布方式与织物结构之间的内在联系,阐述管状织物的成形原理。再次,通过分析织物成形过程,定义了底盘工艺单元,然后基于管状织物的成形原理提出了等效角轮单元的选取原则,从而构建六角形编织机等效角轮系统的底盘结构,确定携纱器的排布方式,接着阐述了携纱器的运动准则,得到可循环执行的工艺步骤。最后,开展了具体的管状织物编织实例设计并进行相关实物编织实验。实验结果验证了编织工艺方法的正确性,该成果将有利于第2代六角形编织机管状编织工艺的快速开发。Objective Hexagonal three-dimensional braiding technology enables more flexible braiding processes,allowing for the fabrication of complex braided structures.The flexibility resulted in challenges such as difficulty in process development and lack of systemization,failing to meet the demands of hexagonal braiding technology.Therefore,a hexagonal braiding technique was proposed for tubular fabric structural design aiming to address these issues.By establishing an inherent connection between fabric structure and braiding machine through equivalent horn gears,the efficiency of hexagonal three-dimensional braiding technology design for tubular fabrics was enhanced.Method Initially,the transfer principle of the yarn carrier on the horn gears was analyzed,and the theory of equivalent horn gears was proposed.Combined with the structure and motion characteristics of the hexagonal braiding machine,the equivalent horn gears unit of the braiding machine was proposed.Subsequently,based on the structural parameters of tubular fabrics,the inherent connection between the arrangement law of the yarn carrier and the fabric structure was established based on the equivalent horn gears.Finally,by analyzing the yarn forming process,the bottom plate process unit was defined.Combining with the principle of tubular fabric forming,the bottom plate structure of the hexagonal braiding machine equivalent horn gears system was constructed,obtaining the arrangement law of the yarn carrier,elucidating the movement criteria of the yarn carrier,and obtaining recyclable process steps.Results Firstly,the principle of carrier position transformation was analyzed,and the theory of equivalent horn gears was proposed.Combined with the structural characteristics of the second-generation hexagonal braiding machine,the equivalent horn gears unit of the second-generation hexagonal braiding machine was proposed,further elucidating the chassis motion unit of the hexagonal braiding machine equivalent horn gears system.Secondly,based on the structural paramet
