羊毛衫收放针搭配的作图求解法研究

Research on diagram for woolen sweater to wide or narrow by needles

现行的毛衫收放针搭配方法主要是直接搭配与方程搭配等代数运算方法,主要存在2方面的不足,一方面设计者往往不能有效地把握羊毛衫收放针搭配后的成形效果;另一方面需要进行较为繁琐的代数运算。为此,文章提出了一种新的羊毛衫收放针搭配方法—作图求解法。在介绍作图求解法基本原理的基础上,着重讨论了几何作图时各直线段的斜率、长度与多组直线组合后的总体趋势等参数的选择,并给出了作图求解的具体步骤与应用实例。

The current method of woolen sweater to wide or narrow by needles is primarily algebra one to directly match or match with equation. The method has two disadvantages, one is that the designer can＇t usually grip full woolen sweater shape with confidence; another is that is need to be proceeded tedious algebra to calculate.This paper gives a new method of woolen sweater to wide or narrow by needles,which is making a diagram. According as the basic principle of the method, it discusses mostly the parameter choice for the slope and weight of straight line segment, total trend for the combination of straight line segments. Concrete steps and two examples are gave out.
