摘要：

为提高无缝成形产品设计系统效能,在研究设计特点与款式成形结构原理的基础上,对无缝成形产品的工艺设计模型进行研究。通过对无缝成形产品工艺的数学建模,分别建立款式、花型图数学模型,用数学语言描述花型图的意匠信息。建立了结构花型图模型来描述花型图与编织行的关系,直观地表现纱线编织状态。结果显示:立体花型图的设计赋予了意匠格更多维度的信息,可以同时控制步进、纱嘴的动作;结合设计模型,通过色块分区、组织填充和图元贴图功能实现了产品的工艺设计,简化了工艺设计流程,实现了规范与高效的无缝成形产品设计系统。

关键词: 纬编, 无缝成形产品, 数学模型, 设计系统

Abstract:

In order to develop a weft-knitted product design system, this paper studies the process design model of weft knits based on studying the design characteristics and the structural principle of style forming. The research content includes the mathematical modeling method for weft knitted product pattern process, the mathematical models of design, and creation of process pattern diagram respectively.The information of the pattern was described in mathematically, and the structural pattern diagram describes the relationship between the pattern diagram and the knitting row and visually represents the knitting state of the yarn. The design of the overlapping pattern gives more dimensional information and can control the movement of the motor and yarn finger at the same time. Combined with the design model, the process design of the product was realized through the function of color block partition organization, filling and element mapping, which simplified the process design process and realized the standard and efficient weft knitted product design system.

Key words: weft-knitted, seamless product, mathematical model, design system
