摘　　要：基于四步法(1×1)编织技术的基本原理,对编织过程中携纱器的周期性运动及纱线在空间中所呈现轨迹进行了详细分析。利用Matlab软件定义了两个二元变量,以编程形式追踪携纱器的规律性运动。根据纱线一系列假设条件,采用内胞表征三维编织复合材料内部结构,建立了三维四向结构单胞模型。同时,给出纱线的空间坐标,利用Texgen软件完成了对三维编织复合材料预制体的建模。Based on the basic principles of the four-step method(1×1) weaving technology,a detailed analysis is conducted on the periodic motion of the yarn carrier and the trajectory of the yarn in space during the weaving process.Utilizing Matlab software,two binary variables are defined to track the regular movement of the yarn carrier in a programmatic form.Based on a series of hypothetical conditions for the yarn,the internal structure of three-dimensional woven composite materials is represented using an inner cell characterization,and a three-dimensional four-directional structure unit cell model is established.Meanwhile,by providing the spatial coordinates of the yarn,the modeling of the three-dimensional woven composite material preform is completed using Texgen software.
