本文主要对四步法编织技术的特点进行了分析，并根据其编制的特点在计算机相关软件模拟了编制纱线的运 动轨迹，采用计算机图形技术显示出三维编织的结构，利用计算机将三维四步法编制复合材料的设计和实现过程模拟出来。 以编织工艺参数的关系为依据，在计算机软件中设置仿真参数，以便于各种尺寸和编制角的三维编织模型的生成，这种计算机 模拟方法能够让模型无限接近编织物的真实结构。

This article mainly analyzes the characteristics of the four-step braided technology, and simulates the motion track of the yarn according to the braiding characteristics in computer. It uses computer graphic technology to show the 3d braided structure, and simulates the design and implementation of braided composites with three-dimensional four-step approach. On the basis of the relationship of braiding parameters, simulation parameters are set in the computer software, so as to generate the 3d braided model in variety of sizes and angles, which can be infinitely close to the real structure model of the braid.
