经编针织物CAD系统的数据结构设计

Data structure design of the CAD system for warp knitted fabric

根据经编针织物CAD软件的开发和使用环境,选择了一种单表数据存储结构。通过经编针织物的垫纱运动和穿经循环描述,设计了CAD系统中梳栉节点、穿经节点和线圈节点的数据结构,并举例阐述3个主要数据结构在经编针织物CAD系统中的应用。

According to the development of CAD software for knitted fabrics and its operating environment, a single data table store structure is selected in this paper. According to the description of the lapping movements and drawing-in cycle of warp knitted fabric, this paper designs the data structure of the guide bar node, drawing-in node and the stitch node, and lists the applications of the 3 main data structures in the CAD of warp knitted fabrics.
